Question

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 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 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 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 up at a faster speed because the child has less mass

Answer 1

The child will move up at a slower speed because the child has less mass.

When the mother jumps and comes back down, her kinetic energy is transferred to the child through the bouncy house floor. However, since the child has less mass, the effect of that energy transfer will cause the child to move upward but at a slower speed than that of the mother's descent.
