Question
A commuter is driving a car along a straight road at a constant speed of 16.5 m/s. Just as she passes a law officer parked along the side of the road, the officer starts to accelerate 1.00 m/s² to overtake her. Assume that the officer maintains this acceleration.
(a) From the moment the commuter passes the officer, determine the time it takes the officer to reach the commuter (in s).
(b) Find the speed of the officer as he overtakes the commuter (in m/s).
m/s
(c) Find the total displacement of the officer as he overtakes the commuter (in m).
m
(d) What If? Determine the answers to parts (a) through (c) of the problem, if instead of accelerating at the same instant the car passes him, the officer instead begins his acceleration 1.00 s after the car passes him. (Enter the time in s, speed in m/s, and
displacement in m.)
