Question

A ball rolls down a hill and hits a box. The momentum of the ball decreases. Which happens to the momentum? Select one of the options below as your answer:
a. It is transferred to the box.
b. It is converted to inertia.
c. It is converted to mass.

Answer 1

So we want to know what happens to the momentum of the ball that rolls down hill and hits a box. So we need to use the law of conservation of momentum which states that the momentum must be conserved. It cant be transformed into inertia or mass. It can only be transferred to other object via some interactions like collisions. So it has to be a. transferred to the box and that is the correct answer.
