Explain how the design of a racing car makes it less likely to turn over.​

Answers

The principles which allow aircraft to fly are also applicable in car racing. The only difference being the wing or airfoil shape is mounted upside down producing downforce instead of lift. The Bernoulli Effect means that: if a fluid (gas or liquid) flows around an object at different speeds, the slower moving fluid will exert more pressure than the faster moving fluid on the object. The object will then be forced toward the faster moving fluid. The wing of an airplane is shaped so that the air moving over the top of the wing moves faster than the air beneath it. Since the air pressure under the wing is greater than that above the wing, lift is produced. The shape of the Indy car exhibits the same principle. The shape of the chasis is similar to an upside down airfoil. The air moving under the car moves faster than that above it, creating downforce or negative lift on the car. Airfoils or wings are also used in the front and rear of the car in an effort to generate more downforce. Downforce is necessary in maintaining high speeds through the corners and forces the car to the track. Light planes can take off at slower speeds than a ground effects race car can generate on the track. An Indy ground effect race car can reach speeds in excess of 230 mph using downforce. In addition the shape of the underbody (an inverted wing) creates an area of low pressure between the bottom of the car and the racing surface. This sucks the car to road which results in higher cornering speeds.

The total aerodynamic package of the race car is emphasized now more than ever before. Teams that plan on staying competitive use track testing and wind tunnels to develop the most efficient aerodynamic design. The focus of their efforts is on the aerodynamic forces of negative lift or downforce and drag. The relationship between drag and downforce is especially important. Aerodynamic improvements in wings are directed at generating downforce on the race car with a minimum of drag. Downforce is necessary for maintaining speed through the corners. Unwanted drag which accompanies downforce will slow the car. The efficient design of a chassis is based on a downforce/drag compromise. In addition the specific race circuit will place a different demand on the aerodynamic setup of the car.

A road course with low speed corners, requires a car setup with a high downforce package. A high downforce package is necessary to maintain speeds in the corners and to reduce wear on the brakes. This setup includes large front and rear wings. The front wings have additional flaps which are adjustable. The rear wing is made up of three sections that maximize downforce.

The speedway setup looks much different. The front and rear wings are almost flat and are used as stabilizers. The major downforce is found in the shape of the body and underbody. Drag reduction is more critical on the speedway than on other circuits. Since the drag force is proportional to the square of the speed, minimizing drag is a primary concern in the speedway setup. Lap speeds can average over 228 mph and top speeds can exceed 240 mph on a speedway circuit. Effective use of downforce is especially pronounced in highspeed corners. A race car traveling at 200 mph. can generate downforce that is approximately twice its own weight.

Generating the necessary downforce is concentrated in three specific areas of the car. The ongoing challenge for team engineers is to fine tune the airflow around these areas.

A hiker walks 5.0 kilometers due north for twenty minutes. He turns due west and travels 12 kilometers in 60 more minutes. Then he walks 7.0 kilometers due north in forty minutes. What is the average speed of the hiker when traveling north?

Answers

Answer:

The hikers average speed due north is 0.2 km per minute.

Explanation:

Speed is the ratio of distance moved by a body to the time taken.

i.e speed = [tex]\frac{distance}{time}[/tex]

Since the hiker walks due north and due west, then his average speed due north can be determined by;

Average speed = [tex]\frac{total distance due north}{total time taken}[/tex]

Total distance due north = 5.0 + 7.0

                                  = 12.0 km

Total time taken = 20 + 40

                           = 60 minutes

                           = 1 hour

Average speed due north= [tex]\frac{12}{60}[/tex]

                          = [tex]\frac{1}{5}[/tex]

                          = 0.2

Average speed due north = 0.2 km/minute

The hikers average speed due north is 0.2 km per minute.

An astronaut sitting on the launch pad on Earth's surface is 6,400 kilometers from Earth's center and weighs 400 newtons. Calculate her weight when she reaches an altitude of 6,400 kilometers above the surface of Earth.

Answers

Answer:

weight at height = 100 N .

Explanation:

The problem relates to variation of weight  due to change in height .

Let g₀ and g₁ be acceleration due to gravity , m is mass of the object .

At the surface :

Applying Newton's law of gravitation

mg₀ = G Mm / R²

At height h from centre

mg₁ = G Mm /h²

Given mg₀ = 400 N

400 = G Mm / R²

400 = G Mm / (6400 x 10³ )²

G Mm = 400 x (6400 x 10³ )²

At height h from centre

mg₁ =  400 x (6400 x 10³ )²/ ( 2 x 6400 x 10³)²

= 400 / 4

= 100 N .

weight at height = 100 N

A student pushed a box 27.0 m across a smooth, horizontal floor using a constant force of 113 N. If the force was applied for 9.00 s, how much power was developed, to the nearest watt? Round your answer to the nearest whole number.

Answers

339 Watts

Nm/s=Watts.
113N * 27m / 9s
339 Watts

The power is a dependent parameter on work done for a given interval of time. The magnitude of power developed due to the applied force is 339 W.

What is power?

The rate of doing work is known as Power. Mathematically, the power is equal to the ratio of work and time interval.

Given data -

The distance covered by the box is, d = 27.0 m.

The magnitude of the constant force is, F = 113 N.

The time interval for the application of force is, t = 9.00 s.

The expression for the power developed is given as,

P = W/t

here, W is the work done and its value is, W = F × d.

Solving as,

P = F × d/t

Solving as,

P = 113 × 27.0/9.0

P = 339 W

Thus, we can conclude that the magnitude of power developed due to the applied force is 339 W.

Gravitational Attraction between the objects:

We know the formula:

g = G(m₁)(m₂) / r² ,where G is the universal Gravitational Constant and g is the force of attraction

g = (6.67 * 10⁻¹¹ * 3 * 10³ * 4.5 * 10³) / (1.5)²

g = [(6.67 * 3 * 4.5) * (10³⁺³⁻¹¹)] / 2.25

How high did a worker lift a 25 kg bag of sand if it now has 2940 of gravitational potential energy

Answers

Answer:

12 m

Explanation:

From the question given above, the following data were obtained:

Mass (m) of bag = 25 kg

Potential energy (PE) = 2940 J

Height (h) =?

Objects carried to a particular height will always experience an acceleration due to gravity of 9.8 m/s².

With the above in mind, we can obtain the height to which the load is lifted to as shown below:

Mass (m) of bag = 25 kg

Potential energy (PE) = 2940 J

Acceleration due to gravity (g) = 9.8 m/s².

Height (h) =?

PE = mgh

2940 = 25 × 9.8 × h

2940 = 245 × h

Divide both side by 245

h = 2940 / 245

h = 12 m

Therefore, the worker lifts the load to a height of 12 m.

D. 90km/h West

Answers

Answer:

D. 90km/hr due West

Explanation:

Given parameters:

Displacement  = 1215km

Time  = 13.5hr

Unknown:

Velocity  = ?

Solution:

Velocity is the displacement divided by the time taken;

   Velocity  = [tex]\frac{displacement}{time}[/tex]   = [tex]\frac{1215km}{13.5hr}[/tex]   = 90km/hr

Velocity is 90km/hr due West
