As shown below, a box slides on a flat horizontal surface towards a spring. When the box hits the spring, it compresses the spring a distance x and finally is brought to rest (momentarily). Use the following information for this problem. Jud (i) The box has mass m. (ii) The surface is frictionless. (iii) The force constant of the spring is k. (iv) The initial speed of the box is v. How much is the spring compressed from its natural length at the moment that the box comes momentarily to rest? Show your work.
