### Kinematics

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.)
