A wildebeest and a chicken participate in a race over a 1.80 km long course. The wildebeest travels at a speed of 20.0 m/s and the chicken can do 3.90 m/s. The wildebeest runs for 1.440 km and then stops to tease the slow-moving chicken, which eventually passes by. The wildebeest waits for a while after the chicken passes and then runs toward the finish line. Both animals cross the finish line at the exact same instant. Assume both animals,...

Near the end of a marathon race, the first two runners are separated by a distance of 45.0 m. The front runner has a velocity of 3.45 m/s, and the second a velocity of 4.25 m/s. (a) What is the velocity(in m/s) of the second runner relative to the first? m/s faster than the front runner (b) If the front runner is 250 m from the finish line, who will win the race, assuming they run at constant velocity O...

Winning an interstellar race, Mavis pilots her spaceship across a finish line in space at a speed of 0.600 relative to the line. A "hooray" message is sent from the back of her ship (event 2) at the instant (in her frame of reference) that the front of her ship crosses the line (event 1). She measures the length of the ship to be 300m. Stanley is at the finish line and is at rest relative to it. When and...

Two boats start together and race across a 46-km-wide lake and back. Boat A goes across at 46 km/h and returns at 46 km/h. Boat B goes across at 23 km/h, and its crew,realizing how far behind it is getting, returns at 69 km/h. Turnaround times are negligible, and the boat that completes the round-trip first wins.

Two runners in a 100 m race start from the same place. Runner A starts as soon as the starting gun is fired and runs at a constant speed of 8.00 m/s. Runner B isn’t really paying attention and starts running 2.0 s later and runs at a constant speed of 9.3 m/s. a. Draw a position vs time graph for each runner. b. Who wins the race? c. At the instant the winner crosses the finish line, how far...

A hare and a tortoise compete in a race over a straight course 0.90 km long. The tortoise crawls at a speed of 0.300 m/s toward the finish line. The hare runs at a speed of 7.90 m/s toward the finish line for 0.720 km and then stops to tease the slow-moving tortoise as the tortoise eventually passes by. The hare waits for a while after the tortoise passes and then runs toward the finish line again at 7.90 m/s....
