Suppose the race car now slows down uniformly from 56.5 m/s to 29.0 m/s in 3.70 s to avoid an accident, while still traveling a circular path 4.40 x 102 m in radius. (a) Find the magnitude of the centripetal acceleration when the speed is 40.0 m/s. m/s (b) Find the angular speed when the speed is 40.0 m/s. rad/s (c) Find the magnitude of the tangential acceleration when the speed is 40.0 m/s. m/s (d) Find the magnitude of the total acceleration when the speed is 40.0 m/s. m/s
