Answer:

239.2 N

Explanation:

Given that a vertical rope is attached to an object that has a mass of 40.0 kg and is at rest.The tension in the rope needed to give the object an upward speed of 3.50 m/s

in 0.700 s is

The tension in the rope and the weight of the mass will be acting in an opposite direction.

T - mg = ma ....... (1)

Where acceleration a = Velocity/ time

a = 3.5 / 0.7

a = 5 m/s^2

Substitutes acceleration a into the equation 1 above.

T - 40 × 9.8 = 40 × 5

T - 39.2 = 200

T = 200 + 39.2

T = 239.2N

Therefore, the tension in the rope needed to give the object an upward speed of 3.50 m/s

in 0.700 s is 239.2N

Answer:

The answer is T=592 N

Explanation:

Fw= 392N

a=v/t, so a=3.5ms^-1/0.7s

a=5ms^-2

Fnet=ma

T-Fw=ma

T-392N=40kg(5ms^-2)

T=592N

A car travels at a constanT

Answer:

Michael is heavier.

Explanation:

If Michael is 104 pounds, that is equal to 47 kg.

Erica is 44 kg which is 97 pounds.

104 is greater than 97, and 47 is greater than 44.

Answer:

Michael weighs more

Explanation:

First, you need to convert either kilograms into pounds or pounds into kilograms. For this problem, I will convert kilograms into pounds.

Multiply 44kg by 2.2 pounds to find how many pounds are in 44 kg

44 x 2.2 = 96.8 pounds

Michael - 104 pounds

Erica - 96.8 pounds

Michael is heavier than Erica because he weighs 7.2 pounds more than her.

(pounds to kilograms - 104/2.2 = 47.3 kg   Michael weighs 7.3 kilograms more than Erica)

Answer:

I hope this answer is correct

Explanation:

The mechanical advantage of a machine is 4. Mechanical advantage MA is the ratio of output (generated by the machine) force to input (applied to the machine) force. So MA = 4 means that for example if you apply 100 N then your machine will multiply that force and generate 400 N.

Answer:

Explanation:

The acceleration of an object given it's velocity and time taken can be found by using the formula

[tex]a = \frac{v}{t} \\ [/tex]

where

v is the velocity

t is the time

From the question

v = 450 m/s

t = 15 s

We have

[tex]a = \frac{450}{15} \\ [/tex]

We have the final answer as

Answer: if this is the same question I think it’s 24

Explanation:

Answer:

According to Newton's second law of motion, acceleration is directly proportional to force. As the force increases (when mass is constant), the acceleration increases. This can be shown in the following formula.

[tex]f = ma[/tex]

[tex]a = \frac{f}{m} [/tex]

f = force

m = mass

a = acceleration

According to Newton's second law of motion, acceleration is directly proportional to the force.

According to Newton's second law of motion, an object's change in velocity is influenced by the force being applied to it. An object must accelerate in order to change its velocity. The rate at which an object's velocity alters over time is known as its acceleration.

Since both acceleration and force are vector quantities, the acceleration of an object is determined by the direction of the applied force. How much a net force will alter an object's velocity is described by Newton's second law of motion.

According to Newton's second law of motion, an object's acceleration is directly proportional to the force acting on it.

Given : Acceleration of the ball is 9.8 m / s² . The pulling force is 1.4 N .

To Find : The mass of the ball .

Solution : It is given that a ball accelerates download with a acceleration of 9.8 m / s² . And the acting force is 1.4 N .

We know that , Force acting is equal to the product of mass and acceleration . That is ,

[tex]\boxed{\purple{\bf Force=mass\times acceleration}}[/tex]

⇒ Force = mass × accelerⁿ

⇒ 1.4 N = mass × 9.8 m / s²

⇒ mass = 1.4 N / 98 m/s²

⇒ mass = 14N / 98 m/s².

⇒ mass = 1/7 kg .

Hence the mass of the object is 1/7 kg ≈ 0.14 kg.

Answer:

The focus of Lesson 1 is Newton's first law of motion - sometimes referred to as the law of inertia. Newton's first law of motion is often stated as. An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

Explanation:

Answer:

Newton's first law is also called the law of Inertia.

Explanation:

The property of a body by virtue of which it wants to remain in its position, is called inertia.

Mainly there ae three types of inertia-

Inertia was discovered by Galileo and it was modified by Newton.

If a body is in motion or in rest, it wants to remain in its position unless any external force is applied.

Thus Newton's first law of motion is also called law of inertia.

Answer:

8 times

Explanation:

Given that You have about 10 quarts of blood in your body. At REST your heart pumps about 5 quarts each minutes.

That means the heart will pump 10 quarts in 2 minutes.

That is half of your blood volume per minute.

If during exercise it can pump 40 quarts per minute, that is, 80 quarts in 2 minutes.

To know how many times does all of your blood complete the cycle around your body during exercise, you must divide 80 quarts by 10 quarts. That is,

80 / 10 = 8

Therefore, your blood complete the cycle around your body 8 times during the exercise.

Answer:

32cm³

Explanation:

Given parameters:

  Density of substance  = 2.7g/cm³

   Mass of substance  = 86.4g

Unknown:

Volume of substance  = ?

Solution:

Density is the mass per unit volume of a substance.

    Density  = [tex]\frac{mass}{volume}[/tex]

Since the unknown is volume we solve for it;

   mass  = density x volume

   86.4 = 2.7 x volume

    volume  = [tex]\frac{86.4}{2.7}[/tex]   = 32cm³

Answer:  

2

Explanation:

Answer:

Yes

Explanation:

A position describes the position of an object relative to the x/y-axis (or the four cardinal directions). A velocity is a vector quantity, defining speed with direction.

So if an object is in a positive position, it means they are in the positive x-axis direction (or wherever on the scale the positive values are stated to be) and if it has a negative velocity, it means said object is moving in the opposite direction of the positive x-axis. It is possible for the object to still be in the positive position as it's moving with a negative velocity
