In an engine, a piston oscillates with simple harmonic motion so that its position varies according to the following expression, where x is in centimeters and t is in seconds. x = (5.00 cm) cos(t + ?/7)
(a) At t = 0, find the position of the piston. Correct: Your answer is correct. cm
(b) What is its velocity? Incorrect: Your answer is incorrect. Your response differs from the correct answer by more than 100%. cm/s
(c) What is its acceleration? Incorrect: Your answer is incorrect. Your response differs from the correct answer by more than 100%. cm/s2
(d) Find the period and amplitude of the motion. s cm
