Constant Acceleration Kinematics: A car is moving with a speed of 32.0 m/s. The driver sees an accident ahead and slams on the brakes, causing the car to slow down with a uniform acceleration of magnitude 3.50 m/s2. How far does the car travel after the driver put on the brakes until it comes to a stop?
A. 4.57 m B. 9.14 m C. 112 m D. 146 m E. 292 m
