A 0.500 kg block rests (at x = 0) on a horizontal, frictionless surface as in the figure. The block is pressed back against a spring having a constant of k = 625 N/m, compressing the spring to xi = - 10.0 cm. Then the block is released, and it travels a distance d up an incline with ? = 300 from the horizontal. (10 points)

a)What is the potential energy when the spring is fully compressed?
b)What is the block

    A block of mass 100.0 g rests on a frictionless, horizontal plane. It is pressed firmly against a horizontal spring with spring constant 2000.0 N/m (assume that the spring is massless). The object is held in position such that the spring is compressed 1.00 cm shorter than its undisturbed length. If the block is suddenly released, at what speed will it be traveling when it is free of the spring?
