In the Figure below, we see a 500 gram block resting on the horizontal portion of a "track", whose left end is curved upwards. The horizontal portion of the track is frictionless, except for a 50.0 cm long “rough" portion, shown in the Figure, where the coefficient of kinetic friction is 0.300. The curved portion of the track is frictionless. The block is held against a spring (which has a stiffness constant of 500 N/m), compressing the spring by 10.0 cm. Then the block is released from rest. (NOTE: The block is not attached to the spring; it is just held against the end of the spring.) For simplicity, assume that g = 9.80 m/2. 50.0 cm
