A vehicle is moving at 50 mph and suddenly sees an object. It applies the brakes and slows down to a speed of 15 mph. Calculate the following: a. Distance the vehicle would move before driver activates the brakes. (Use design PIEV time of 2.5 seconds) b. distance the vehicle moved after application of brakes to drop to 15 mph speed (assume constant Ideceleration rate of 11.2 ft/sec²)
