Question

A student has 2 rubber balls of the same size and weight. Ball A is still and Ball B is rolling.Ball B hits Ball A, and Ball A start moving. Why does Ball A start moving?

A). Ball A is repelled by Ball B ,
B). Ball B is attracted to Ball A ,
C). Ball B transfers energy to Ball A ,
D). Ball A transfers energy to Ball B

Answer 1

c

Step-by-step explanation:

Answer 2

C). Ball B transfers energy to Ball A

Step-by-step explanation:

The motion of ball A is a because of the energy it acquires.

Ball A initially due to its position posses potential energy due to its position.

The moving ball B has kinetic energy due to the motion of this ball.

• Due to the collision, momentum is transferred from the moving ball to the static one.
• As the momentum of the static ball changes, potential energy is converted to kinetic energy.
• The magnitude of the energy possessed by the static ball must be lesser than that of the moving.
