Chapter 2, Problem 112PP
Referring to Example 2-17 Suppose the speeder (red car) is traveling with a constant speed of 25 m/s, and the maximum acceleration of the police car (blue car) is 3.8 m/s2. If the police car is to start from rest and catch the speeder in 15 s or less, what is the maximum head-start distance the speeder can have? Measure time from the moment the police car starts.

Two cars are moving along a straight line AB. Car A starts from rest from
point A and moves toward point B The acceleration of car A starts from (0) m/s
and increases at a rate of( 2 m/s2/s) ( means a=2t m/s?). Car B starts form B and
moves toward A. The acceleration of B starts from (0) m/s' and increases by a rate
of (4m/s'/s). Both cars are met at a distance of (2/3) of total AB distance as measured
from A. Find :
I-the velocity of each car when they met.
ii-Length of AB in m.
The takeoff time t =
2.42 s looks as a reasonable numerical value.
Example 2-2
You are driving down the highway late one night at 58 mph when a deer steps into the road 50 m
(about 164 ft) in front of you. Your reaction time before stepping on the brakes is 0.5 s, and the
maximum deceleration of your car is 9.1 m/s². How much distance is between you and the deer when
you come to stop?
SOLUTION:
I Review
