Assignment:
Constant Acceleration Problem
A motorist traveling with a constant velocity of 15 m/s passes a school-crossing corner. Just as the motorist passes, a police officer stopped on the corner starts off in pursuit with constant acceleration of 2.5 m/s^2 until her speed is 20 m/s. Then she slows down at a constant rate until she comes alongside the car at x = 360m, traveling the same speed of 15 m/s as the car.
a) At what time does the officer catch up to the car?
b) At what time does the officer change from speeding up to slowing down?
c) At this time, how far is the officer from the stop sign?
d) How far behind the car is she?
e) Find the acceleration of the officer while she is slowing down.
