URGENT PLS!
In an engine, a piston oscillates with simple harmonic motion so that its position varies according to the expression, x = 8.00 cos 5t + where x is in centimeters and t is in seconds. (a) At t = 0, find the position of the piston. 6.93 cm (b) At t = 0, find velocity of the piston. -55.4 X How do you find the velocity v(t) of an object if you know the position as a function of time, x(t)? cm/s (c) At t = 0, find acceleration of the piston. -110.85 How do you find the acceleration a(t) of an object if you know the velocity as a function of time, v(t)? cm/s² (d) Find the period and amplitude of the motion. period S amplitude cm
