A 0.10 kg block oscillates back and forth along a straight line on a frictionless horizontal surface. Its displacement from the origin is given by x = (10 cm) cos [(10 rad/s)t + π/2 rad].
(a) What is the oscillation frequency?
(b) What is the maximum speed acquired by the block?
(c) At what value of x does this occur?
(d) What is the magnitude of the maximum acceleration of the block?
(e) At what value of x does this occur?
(f) What force, applied to the block by the spring, results in the given oscillation?
