A bicycle is moving to the right at a speed of Vo= 20 mph on a horizontal and straight road. The radius of thebicycle's wheels is R = 1.15 ft. Let P be a point on the peripheryof the front wheel. One can show that the x and ycoordinates of P are described by the following functions oftime: and Determine the expressions for the velocity, speed, andacceleration of P as functions of time.
