Chapter 2, Problem 2.32P
Solve Example 2.8 by a graphical method. On the same graph, plot position versus time for the car and the trooper. From the intersection of the two curves, read the time at which the trooper overtakes the car.
Example 2.8 Watch Out for the Speed Limit!
You are driving at a constant speed of 45.0 m/s when you pass a trooper on a motorcycle hidden behind a billboard. One second after your car passes the billboard, the trooper sets out from the billboard to catch you, accelerating at a constant rate of 3.00 m/s2. How long does it take the trooper to overtake your car?

1.) Let sA = 15t^2 + 10t + 20 and
sB= 5t^2 + 40t, where t ≥ 0, be the position functions of cars A and B, respectively, that are moving along parallel straight lanes of a highway (here, t is in minutes
and s in feet).
a.) At what instant of time do they have the same velocity?
b.) Which car is ahead when
the two cars have the same velocity?
Please show your complete solution thanks.
Two cars start from the same point in the same direction, but in the opposite direction. One starts to the right with a speed V1 = 7m / s and the other to the left with speed V2 = 9m / s. The latter, after advancing a distance d = 5m, turns sharply 360º and begins to chase the first car. Decide:
a) At the end of what time it reaches it.
b) How far from the starting point you can reach.
c) The graph of the position as a function of time for both cars.
