Jim is driving at a constant 75.0 mi/hr (33.5 m/s) along a straight section of Route 3 North. The car directly ahead of him is also moving at 75.0 mi/hr. The front bumper of Jim's car is located 18.0 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 7.00 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 Jim 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 Jim effectively applies the brakes, his car slows down at a steady rate of 7.00 m Att 0, the Jim's front bumper is located at X = 0 and the car ahead begins to slow down at a steady 7.00 m/s^2. JIM'S CAR THE CAR AHEAD 75.0 mi/hr 75.0 mi/hr +x 18.0 m 21 Assume, for the sake of argument, that no collision occurs. Starting at t = 0, what distance does car ahead travel while slowing down to 40.0 mi/hr? A. 57.3 m. B. 270 m. C. 288 m. D. 67.0 m. E. 75.3 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 Jim's car is located at x equals A. 56.7 m. В. 101 m. C. 167 m. D. 92.7 m. E. 74.7 m. 23. Assume, for the sake of argument, that no collision occurs. At the instant when Jim effectively applies his brakes, the rear bumper of the car ahead would be located at x equals А. 336 m. B. 306 m. С. 89.1 m. D. 71.1 m. E. 119 m.
