At the instant the traffic light turns green, an automobile starts with a constant acceleration of 2.2 m/s2. At the same instant a truck, traveling with a constant speed of 9.5 m/s, overtakes and passes the automobile.
(a) How far beyond the starting point will the automobile overtake the truck?
(b) How fast will the car be traveling at that instant?
(It is instructive to plot a qualitative graph of x versus t for each vehicle.)
