Answer #1

Impossible statements

1)

The moving motorcycle had 0 J of KE.

Reason : A moving object has some velocity and the expression for kinetic energy is

KE = 1/2 * m * v^2

A moving object never has zero kinetic energy.

All posible statements are

The truck had 0 J of KE and 0 kg∙m/s of momentum.

A ball moving in a circle had 325 N of net force acting on it.

A box had an acceleration of 0 m/s2 while a net force of 0 N acted on it.

Jack exerted 125 N of force due west on a cart. As a direct result, the cart exerted 125 N of force due east upon Jack.

A fork exerts the same gravitational force upon Earth that Earth exerts upon it
