George is driving at a constant 80.0 mi/hr (35.8 m/s) along a straight section of Route 3 North. The car directly ahead of him is also moving at 80.0 mi/hr. The front bumper of George's car is located 28.0 m from the rear bumper of the car ahead when, at t= 0, the driver of the car ahead applies his brakes and begins to slow down at a steady rate of 8.00 2, towards the posted "Construction Zone" speed limit of 40.0 mi/hr (17.9 m/s). After slowing to 40.0 mi/hr, the driver of the car ahead plans to maintain this constant speed. It takes George 2.00 seconds to notice that the car ahead is slowing down, and another 1.00 second to effectively apply his brakes and begin to slow down. Assume that, once George effectively applies the brakes, his car slows down at a steady rate of 8.00 m/2 Att = 0, the George's front bumper is located at X = 0 and the car ahead begins to slow down at a steady 8.00 m/s^2. THE CAR AHEAD GEORGE'S CAR 80.0 mi/hr 80.0 mi/hr 28.0 m 21. Assume, for the sake of argument, that no collision occurs. Starting at t = 0, what distance does the car ahead travel while slowing down to 40.0 mi/hr? A. 107 m. B. 53.7 m. C. 87.9 m. D. 60.1 m. E. 300 m. 22. Assume, for the sake of argument, that no collision occurs. At the instant when the car ahead has slowed to 40 mi/hr, the front bumper of George's car is located at x equals A. 107 m. B. 80.1 m. C. 179 m. D. 53.7 m. E. 240 m. 23. Assume, for the sake of argument, that no collision occurs. At the instant when George effectively applies his brakes, the rear bumper of the car ahead would be located at x equals B. 107 m. A. 87.9 m. C. 73.6 m. D. 179 m. E. 102 m.
