Question

In an engine, a piston oscillates with simple harmonic motion sothat its position varies according to the following expression,where x is in centimeters and t is in seconds. x = (8.00cm) cos(2t +/5) (a) At t = 0, find the position of thepiston.
1 cm

(b) What is its velocity?
2 cm/s

(c) What is its acceleration?
3 cm/s2

(d) Find the period and amplitude of the motion.
4 s
