One end of a horizontal spring with force constant 130.0 N/m is attached to a vertical wall. A 4.00-kg block sitting on the floor is placed against the spring. The coefficient of kinetic friction between the block and the floor is
μk= 0.400. You apply a constant force F, which is directed toward the wall. F has magnitude of 82.0 N and is directed toward the wall. At the instant that the spring is compressed 80.0 cm, what are
(a) the speed of the block, and
(b) the magnitude and direction of the block's acceleration?
