A racecar is driving around the turn on a racetrack at a constant angular velocity of 0.785 rad/s. The experienced commentators can predict the velocity of the driver exiting the turn based upon his angular velocity in the turn. If the coefficient of kinetic friction between the 1500 kg racecar and the racetrack is = 0.5, calculate the velocity (in km/hr) of the driver as he exits the turn. Assume it takes him 4 seconds to go around the bend. [Ans. to Check: 28.28 km/hr]
