The first meters of a 100-meter dash are covered in 2 seconds by a sprinter who starts from rest and accelerates with a constant acceleration. The remaining 90 meters are run with the same velocity the sprinter had after 2 seconds.
a. Determine the sprinter's constant acceleration during the first 2 seconds.
b. Determine the sprinter's velocity after 2 seconds have elapsed.
Suppose several machines launch a rate of 100 tennis balls per second at 80 mph toward a wall where the balls make elastic collisions. Assuming 100 head-on collisions per second, what is the total steady force exerted on the wall? Calculate in New..
