Chapter 2, Problem 7P
Two trains, each having a speed of 30 km/h, are headed at each other on the same straight track. A bird that can fly 60 km/h flies off the front of one train when they are 60 km apart and heads directly for the other train. On reaching the other train, the (crazy) bird flies directly back to the first train, and so forth. What is the total distance the bird travels before the trains collide?

Moving sidewalks are installed every other 50 meters along the entire stretch of an airport walkway. These sidewalks move at a constant speed of 1 m/s. A lady passenger takes one of the sidewalks to go from one point to the next.
If the passenger decides to go back using the same sidewalk at 1 m/s, how long will it take to reach her point of origin?
Car A was traveling east at high speed when it collided at point O with car B , which was traveling north at 45 mi/h. Car C , which was traveling west at 60 mi/h, was 32 ft east and 10 ft north of point O at the time of the collision. Because the pavement was wet, the driver of car C could not prevent his car from sliding into the other two cars, and the three cars, stuck together, kept sliding until they hit the utility pole p. Knowing that the weights of cars A, B, and C are, respectively, 3000 lb, 2600 lb, and 2400 lb, and neglecting the forces exerted on the cars by the wet pavement, solve the problems indicated.Knowing that the coordinates of the utility pole are xp= 46 ft and yp = 59 ft, determine (a) the time elapsed from the first collision to the stop at P,(b) the speed of car A.
