Car Chase
A car (c) with one headlight burned
out is traveling at a constant speed of 18 m/s and passes a stopped
police car (p). The car is pursued
immediately by the police cruiser, which has a constant acceleration
of magnitude 2.2 m/s2.
(a) How far does the police cruiser travel before catching the
other car?
(b) At what time will this occur? (Hint: Graphing may help to
visualize this problem.)
No. At time t2 the two velocities will be equal, but the two cars' displacements will not be equal at the same time. The police cruiser catches up to the car when both cars' displacements are equal.
Try Again.
