A tennis ball has a mass of 57 grams and can easily be served at 80 miles/hr.

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 Newtons, then in pounds.
