##### Reference no: EM13541824

In an engine, a piston oscillates with simple harmonic motion so that its position varies according to the expression, x = 4.00 cos (t +?/5) where x is in centimeters and t is in seconds.

(a) At t = 0, find the position of the piston. . We are given x as a function of time. For any x(t) you can determine the position at a particular time by putting that value into the function. cm

(b) At t = 0, find velocity of the piston. cm/s

(c) At t = 0, find acceleration of the piston. cm/s2

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