The sprockets and chain of a bicycle are shown in the following figure.A chain of a bicycle goes around a pedal sprocket and a wheel sprocket.The radius of the pedal sprocket is 4 in.The radius of the wheel sprocket is 2 in.The radius of the back wheel of the bicycle is 13 in.The pedal sprocket has a radius of 4 in., the wheel sprocket a radius of 2 in., and the wheel a radius of 13 in. The cyclist pedals at 55 rpm.(a)Find the angular speed of the wheel sprocket (in rad/min). rad/min(b)Find the linear speed of the bicycle (in mi/h). (Assume that the wheel turns at the same rate as the wheel sprocket. Round your answer to one decimal place.) mi/h
