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 use a spring having force constant 2k



▸ just as it moves free of the spring, the speed of the box will be times as great as before.

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

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

▸ All of the above choices are correct.

▸ None of the above choices is correct.
