Question

II. Two trains are headed toward each other on collision course on a single, straight track. Each train has a constant speed of 30 mph. When the trains are 60 miles apart a deranged bird starts flying with a constant speed of 60 mph from the front of one train directly toward the other train. When the bird reaches the front of the other train it instantly turns around and flies directly back toward the first train and so on. Assume that the bird has negligible, always flies with the same constant speed (60 mph) and that the turnaround tim is instantaneous. A) Sketch a graph of the motion (x versus t) of both trains and the bird. B) How many trips can the bird make from one train to the other before getting crushed? 2 trips C) What is the total distance the bird travels? 60(1) = 60 km
