A 15-Kg Block Sliding on a Rough Horizontal Surface Is Attached

Multiple Choice

A 1.5-kg block sliding on a rough horizontal surface is attached to one end of a horizontal spring (k = 200 N/m) which has its other end fixed. If this system is displaced 20 cm horizontally from the equilibrium position and released from rest, the block first reaches the equilibrium position with a speed of 2.0 m/s. What is the coefficient of kinetic friction between the block and the horizontal surface on which it slides?

A) 0.34
B) 0.24
C) 0.13
D) 0.44
E) 0.17
