Stopping Distance When the driver of a vehicle observesan impediment, the total stopping distance involves boththe reaction distance (the distance the vehicle travels whilethe driver moves his or her foot to the brake pedal) and thebraking distance (the distance the vehicle travels once thebrakes are applied). For a car traveling at a speed of v milesper hour, the reaction distance R, in feet, can be estimatedby R1v2 = 2.2v. Suppose that the braking distance B, infeet, for a car is given by B1v2 = 0.05v2 + 0.4v - 15.(a) Find the stopping distance functionD1v2 = R1v2 + B1v2. (b) Find the stopping distance if the car is traveling at aspeed of 60 mph.(c) Interpret D1602.

A minivan is tested for acceleration and braking. In the street-start acceleration test. the elapsed time is 8.2s for a velocity increase trom 10 kav/h to 100 km/h. In the braking test, the distance traveled is 44 mi during braking to a stop from 100 knvh. Assuming constant values of acceleration and deceleration, determine to the acceleration during the street-start test, ib) the deceleration during the braking test. Fig. P11.34
