car decelerates uniformly and comes to a stop after 10 s. The car's average velocity during deceleration was 50 km/h. What was the car's deceleration while slowing down?
Help!!!!
Answer:
[tex]a=-1.388\ m/s^2[/tex]
Explanation:
Initial velocity of car, u = 50 km/h = 13.88 m/s
It stops, v = 0
Time, t = 10 s
We need to find the car's deceleration while slowing down. As the car is slowing down, it will have deceleration. It can be calculated as follows :
[tex]a=\dfrac{v-u}{t}\\\\a=\dfrac{0-13.88 }{10}\\\\a=-1.388\ m/s^2[/tex]
So, the deceleration of the car is [tex]1.388\ m/s^2[/tex].

Answer:
hope the answer helped you. pls mark as brainliest
Explanation:
Newton's second law states that the acceleration an object experiences due to a given force is inversely proportional to its mass, that is --
a=Fm
If the acceleration is 10m/s2 and the object's mass is 2kg , we can use Newton's second law to find that:
10m/s2=F2kg
F=20kg m/s2 , or 20N .

Suppose a boat moves at 12.0m/s relative to the water. If the boat is in a river with the current directed east of 2.50m/s, what is the boat's speed relative to the groiund when it is heading (a) east, with the current, and (b) west, against the current?
Answer:
(a) 14.5 m/s
(b) 9.5 m/s
Explanation:
Let the speed of the boat in the still water (i.e relative to ground) is [tex]v_0[/tex].
Given that the speed of the boat relative to water, [tex]v_r=12.0[/tex] m/s.
Speed of the water current of the river relative to the ground, [tex]u_0=2.50[/tex] m/s towards east.
(a) When the boat is heading toward the east (in the same direction of the current of the river)
The relative velocity, [tex]v_r[/tex], of the boat with respect to ground is
[tex]v_r=v_0-u_0[/tex]
[tex]\Rightarrow 12=v_0-2.5[/tex]
[tex]\Rightarrow v_0=12+2.5=14.5[/tex] m/s
Hence, the boat's speed relative to the ground when it is heading east, with the current, is 14.5 m/s.
(b) When the boat is heading toward the west (in the opposite direction of the current of the river)
The relative velocity, [tex]v_r[/tex], of the boat with respect to ground is
[tex]v_r=v_0-(-u_0)[/tex]
[tex]\Rightarrow 12=v_0+2.5[/tex]
[tex]\Rightarrow v_0=12-2.5=9.5[/tex] m/s
Hence, the boat's speed relative to the ground when it is heading west, against the current, is 9.5 m/s.

As the concentration of greenhouse gases in the atmosphere increases, Question 2 options: a) less energy is trapped, which leads to a decrease in Earth's global temperature b) more energy is trapped, which leads to a decrease in Earth's global temperature c) more energy is trapped, which leads to an increase in Earth's global temperature d) less energy is trapped, which leads to an increase in Earth's global temperature
Answer:
c) more energy is trapped, which leads to an increase in Earth's global temperature
Explanation:
Greenhouse effect is caused by the trapping of the reflected energy from the surface of the earth into the atmosphere by some gases. Thus with time causes more energy to be trapped in the atmosphere, which cause an increase in the average ambient temperature of the earth. Because the energy could not escape out into space beyond the earth's atmosphere. Therefore, an increase in Earth's global temperature.
So that the correct option in the given question is C.

Molten (melted) iron and carbon monoxide are produced in a blast furnace by the reaction of iron(III) oxide and pure carbon. Fe2O3 + 3C ---> 2Fe + 3CO If 4 moles of Fe2O3 are used, how many moles of Carbon Monoxide (CO) can be produced?
Answer:
Explanation:
Fe₂O₃ + 3C ---> 2Fe + 3CO
1 mole 3 moles
From the balanced equation above , we see that , 1 mole of Fe₂O₃ reacts with carbon to form 3 moles of CO .
So , 4 moles of Fe₂O₃ will react with carbon to form 3 x 4 moles of CO .

23. A ball is dropped from 215m. How long will it take to reach the ground?
Answer:
6.6 s.
Explanation:
From the question given above, the following data were obtained:
Height (h) = 215 m
Time (t) =..?
Thus, we can obtain the time taken for the ball to get to the ground by applying the following formula:
h = ½gt²
Where:
h is the height.
g is the acceleration due to gravity
t is the time to taken.
With the above formula, the time taken for the ball to get to the ground can be obtained as follow:
Height (h) = 215 m
Acceleration due to gravity (g) = 9.8 m/s²
Time (t) =..?
h = ½gt²
215 = ½ × 9.8 × t²
215 = 4.9 × t²
Divide both side by 4.9
215 / 4.9 = t²
Take the square root of both side.
t = √(215 / 4.9)
t = 6.6 s
Therefore, it will take 6.6 s for the ball to get to the ground.

b) What is the acceleration of Dan’s car?
Answer:
76.53 kg; 9.15 m/s² left.
Explanation:
Given the following data;
Weight of car = 750N
Applied force = 700N
a) To find mass
Weight can be defined as the force acting on a body or an object as a result of gravity.
Mathematically, [tex] Weight, W = mg[/tex]
We know acceleration due to gravity is equal to 9.8 m/s²
Substituting into the equation;
[tex] 750 = m*9.8[/tex]
[tex]Mass, m = \frac{750}{9.8}[/tex]
Mass, m = 76.53kg
b) To find the acceleration;
Force is given by the multiplication of mass and acceleration.
Mathematically, Force is;
[tex] F = ma[/tex]
Where;
F represents force.m represents the mass of an object.a represents acceleration.Making acceleration (a) the subject, we have;
[tex]Acceleration (a) = \frac{F}{m}[/tex]
Substituting into the equation;
[tex]Acceleration (a) = \frac{700}{76.53}[/tex]
Acceleration (a) = 9.15 m/s² left.
