A gazelle and a mouse participate in a race over a 2.00 km long course. The gazelle travels at a speed of 15.0 m/s and the mouse can do 2.50 m/s. The gazelle runs for 1.600 km and then stops to tease the slow-moving mouse, which eventually passes by. The gazelle waits for a while after the mouse passes and then runs toward the finish line. Both animals cross the finish line at the exact same instant. Assume both animals, when moving, move steadily at their respective speeds. (a) How far (in m) is the mouse from the finish line when the gazelle resumes the race? m (b) For how long in time (in s) was the gazelle stationary?
