A 0.15 kg block oscillates back and forth along a straight line on a frictionless horizontal surface. Its displacement from the origin is given by
x = (20 cm)cos[(11 rad/s)t + Ï/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 positive value of x does this occur?
(f) What force, applied to the block by the spring, results in the given oscillation?
