6.

If an astronaut were to exert a force on a ball, the ball would

A. Fall downward

B. Exert a force on the astronaut

C. Make the astronaut fall

D. Stop

Answer 1

Hello!

The correct answer is B. Exert a force on the astronaut.

When the astronaut exerts a force onto an object, the object exerts just as much force back onto him. This is Newton's Third Law; "equal in magnitude but opposite in direction."

I hope this helps you! Have a lovely day!

Answer 2

If an astronaut were to exert a force on a ball, the ball would exert a force on the astronaut.

Answer: Option B

Step-by-step explanation:

If an astronaut applies force on the ball, same force will be applied on astronaut. It is universal as also according to Newton’s 3rd law. But, in space, there is no force of gravity. And so, the masses need not be considered.

If he pushes the ball with a force, and it gains some velocity v, the astronaut himself, will attain the same velocity. This is because, in space, no object attracts a mass. Astronaut fall is also correct if he applies a large amount of force while pushing.
