A 16-pound bowling ball strikes a 3.5-pound bowling pin. The pin is moving very fast after the collision. It has a large increase in velocity as a large amount of kinetic energy is transferred to it. Where does the energy come from?(1 point)
Responses
It is lost by the bowling ball, which would have an equal decrease in velocity.
It is lost by the bowling ball, which would have an equal decrease in velocity.
It is lost by the bowling ball, which would have a smaller decrease in velocity.
It is lost by the bowling ball, which would have a smaller decrease in velocity.
It is lost by the bowling ball, which would have no change in velocity.
It is lost by the bowling ball, which would have no change in velocity.
It is lost by the bowling ball, which would have a larger decrease in velocity.

A mother and her small child are standing in an inflatable bouncy house on opposite sides. The mother jumps up and comes back down again, transferring her kinetic energy to the child through the floor. How will the motion of the small child change?(1 point)
Responses
The child will move up at the same speed at which the mother came down.
The child will move up at the same speed at which the mother came down.
The child will move down at the same speed at which the mother came down.
The child will move down at the same speed at which the mother came down.
The child will move up at a slower speed because the child has less mass.
The child will move up at a slower speed because the child has less mass.
The child will move up at a faster speed because the child has less mass.
