A box of mass m is pressed against (but is not attached to) an ideal spring of force constant k and negligible mass, compressing the spring a distance x. After it is released, the box slides up a frictionless incline as shown in the figure and eventually stops. If we repeat this experiment but instead compress the spring a distance of 2x



▸ the box will go up the incline twice as high as before.

▸ just as it moves free of the spring, the box will have twice as much kinetic energy as before.

▸ just as it moves free of the spring, the box will be traveling twice as fast as before.

▸ just as it moves free of the spring, the box will be traveling four times as fast as before.

▸ just before it is released, the box has twice as much elastic potential energy as before.
