Solve the below problem:
Q: A 10-lb block A rests on a 40-lb plate B which is attached to an un-stretched spring of constant k = 60 lb/ft. Plate B is slowly moved 2.4 in. to the left and released from rest. Assuming that block A does not slip on the plate, determine
(a) The amplitude and frequency of the resulting motion,
(b) The corresponding smallest allowable value of the coefficient of staticfriction.
