Problem 3-7 The acceleration of a vehicle takes the form du dt (i3.6-0.06u where u is the vehicle speed in fsec. The vehicle is traveling at 45 f/sec at time To. (a) Determine the distance traveled by the vehicle when accelerated to a speed of 55 ft/sec. (b) Determine the time at which the vehicle attains the speed of 55 ft/sec. (c) Determine the acceleration of the vehicle after 3 sec.

A value commonly taken for the perception reaction time of motorists is delta t equals 1.5 seconds. Using this value determine the total stopping distance for a car traveling at 30 m/s. In calculating the stopping distance, lets assume that the vehicle continues at its initial speed for delta t, then decelerates to rest. A reasonable value for the deceleration in braking is 8.0 m/s^2
