Concept explainers
A five-foot-tall boy tosses a tennis ball straight up from the level of the top of his head. Neglecting frictional forces, the subsequent motion is governed by the differential equation
If the object hits the ground 8 seconds after the boy releases it, find
(a) The time when the tennis ball reaches its maximum height.
(b) The maximum height of the tennis ball.

- The kinetic energy E of an object varies jointly with the object’s mass m and the square of the object’s velocity v . An object with a mass of 50 kilograms traveling at 16 meters per second has a kinetic energy of 6400 joules.
