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 mk = 0.400. You apply a constant force F to the block. F has magnitude F = 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?

Question

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 mk = 0.400. You apply a constant force F to the
block. F has magnitude F = 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?
