1.a baseball hits a home run, according to Newton's laws of motion which of the following statements could be true in this scena

rio:
statement 1: the bat pushes on the ball with the same force as the ball pushes on the bat.

statement 2: Newton's 2nd law explains why the ball travels farther than the bat.

statement 3: the bat hit the ball causing the ball to change direction. this is an example of unbalanced force in Newtons first law of motion.

choose all statements that are true.

2. A bowling ball on earth weighs 11 pounds and has a mass of 5kg. The gravitational pull on the moon is 1/6 of the gravitational force on earth. what would the mass of the bowling ball be on the moon?

3.how much force would you need to use in order to accelerate an 80kg shopping cart to 0.2 m/s^2 (f=ma)?

<h2>Answer to Q1:  </h2>

<u>The correct option is </u><u>bat pushes on the ball with the same force as the ball pushes on the bat. </u>

<h2>Explanation: </h2>

According to Newton’s law action and reaction are equal in magnitude but opposite in direction so the same case will apply here. The bat pushes on the ball with the same force as the ball pushes on the bat just the direction is opposite.

<h2>Answer to Q2 </h2>

Mass will remain the same

<h2>Explanation: </h2>

The gravitational pull is related to the weight of objects. Weight is the force with which earth attracts everything towards its centre. And mass is the quantity of matter inside the body. So on the moon the quantity of matter inside a body does not change therefore the mass would remain the same.

<h2>Answer to Q3 </h2>

Force required is 16 Newton

<h2>Explanation: </h2>

Mass= 80 kg

Acceleration = a = 0.2

So F = ma

Putting the values

F= 80 x 0.2

F = 16 N

Three observers watch a train pull away from a station toward the right of the platform. Observer A is in one of the train’s car
juin [17]

Observer A is moving inside the train

so here observer A will not be able to see the change in position of train as he is standing in the same reference frame

So here as per observer A the train will remain at rest and its not moving at all

Observer B is standing on the platform so here it is a stationary reference frame which is outside the moving body

So here observer B will see the actual motion of train which is moving in forward direction away from the platform

Observer C is inside other train which is moving in opposite direction on parallel track. So as per observer C the train is coming nearer to him at faster speed then the actual speed because they are moving in opposite direction

So the distance between them will decrease at faster rate

Now as per Newton's II law

F = ma

Now if train apply the brakes the net force on it will be opposite to its motion

So we can say

- F = ma

a = \frac{-F}{m}

so here acceleration negative will show that train will get slower and its distance with respect to us is now increasing with less rate

It is not affected by the gravity  because the gravity will cause the weight of train and this weight is always counterbalanced by normal force on the train

So there is no effect on train motion

If you are given the mass of an object in pounds, the time in seconds, and the distance in feet, what must you do before you can
Alexandra [31]

Answer: First you must convert pound in kilogram, and feet in meter

Explanation:

To calculate momentum we use .

p=m*V

mass-m

speed-V

distance and time are used to calculate velocity(speed)

You are given :

 mass- in pounds

for distance - in feet

before you do any calculation first you have to convert pounds in kilograms

and feet in meters.
