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

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) ?

Answer to Q1:

The correct option is bat pushes on the ball with the same force as the ball pushes on the bat.

Explanation:

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.

Answer to Q2

Mass will remain the same

Explanation:

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.

Answer to Q3

Force required is 16 Newton

Explanation:

Mass = 80 kg

Acceleration = a = 0.2

So F = ma

Putting the values

F = 80 x 0.2

F = 16 N
