A 0.46 kg block oscillates back and forth along a straight line ona frictionless horizontal surface. Its displacement from the originis given by
x = (19 cm)cos[(19 rad/s)t + p/2 rad]
(a) What is the oscillation frequency (in Hz)? (b) What is themaximum speed acquired by the block? (c) At what value of x doesthis occur? (d) What is the magnitude of the maximum accelerationof the block? (e) At what positive value of x does this occur? (f)What force, applied to the block by the spring, results in thegiven oscillation?
Give your answers in centimeter-based units, where applicable.
