8) A block of mass 390 g is attached to a spring with spring constant 70 N/m as shown. The spring is compressed 12 cm and then released. Assume that the coefficient of friction is 0.40. a) How much potential energy is stored in the system before the block is released? b) What is the speed of the block as it crosses the point where the spring is neither compressed nor stretched? c) How high up the slope is the block where it just comes to a rest? www. 30°
