The sprinter begins from rest at position A and accelerates along the track. If the stationary tracking camera at O is rotating at the rate of 17.5 deg/s when the sprinter passes the 54-m mark, determine the speed v of the sprinter and the counterclockwise value of r. Part 1 Answers: r= Calculate the distance r, the angle 9, and the rate of rotaion of the camera è in rad/s. 8= i 38 m i 38 m m 0 O 13 m rad/s 13 m
