Problem 2-101 - Linear Kinematics - Part 2 - (a)
A car (c) with one headlight burned out is traveling at a constant speed of 18m/s and passes a stopped police car (p). The car is pursued immediately by the police cruiser, which has a constant acceleration of magnitude 2.2m/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.)
Correct!
The expression relating the car's displacement (xc) to the time (t) is BEST represented by:
(A) xc=x0c+v0ct,withx0c=0
(B) x_c = x_{0c} + v_{0c^t} + ½\; at^2,\text{with} \; x_{0c} = 0
