A piston in an engine moves up and down in its cylinder

A piston in an engine moves up and down in its cylinder in a sinusoidal fashion. The motion of the piston is described by the equation, h = 20 sin (125.66t) +20 where his the height in centimeters and t is the time in seconds. a. What is the period for this scenario? Express your answer to two decimal places. (1 mark) LR b. Suppose the piston operates for one hour. How many complete cycles will it make? (1 mark) Blank # 1 Blank # 2 P
