Car Catches Car
The driver of an automobile, traveling at a constant velocity v1
= 35 m/s, applies his brakes when he is a distance D = 30 m from
a slower moving car that is traveling at a constant v2 =
10 m/s. Assume the car brakes at a constant deceleration
|a1| = 2.2 m/s2.
At what speed is the braking car moving (with respect to the ground)
when it collides with the slowly moving car?
vfg = m/s
