Question

Which type of force is changing the object's speed and direction when a toy clown pops out of a jack-in-the-box?




A.
gravitational



B.
push



C.
magnetism



D. pull

Answer 1

I think it would be d because the spring or whatever was pushing until it reached the farthest it could then it would pull down but idrk

Answer 2

The correct answer is

B. push

To be more precise, the force that changes the speed and direction of the toy clown is the elastic force due to the spring: when the box is closed, the spring is compressed, so all the energy is stored in the elastic potential energy store of the spring. As the box opens, the spring is free to stretch, therefore it pushes the toy out of the box, transferring all the elastic potential energy into kinetic energy of motion of the toy clown.
