A 0.57 kg block oscillates back and forth along a straight line on a frictionless horizontal surface. Its displacement from the origin is given by

x = (13 cm)cos[(20 rad/s)t + π/2 rad]

(a) What is the oscillation frequency (in Hz)? (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?

How do you even start this problem? Please help
