Ball rolls down ramp, collides with toy car, makes the car move. What happened to the energy of ball when it hits car?

• The energy from the ball transferred to the car, making it move forward.

• The ball's energy was absorbed into the ground after the collision.

• The energy of the ball disappeared when it stopped moving.

• The energy remained in the ball, and the car moved on its own.
