Chapter 13.3, Problem 37E

Velocity Work these exercises. (See Example 5.)

A car was driving on a two-lane highway at 80 feet per second (about 55 mph) when it abruptly speeds up to pass a slow-moving truck. The velocity of the car (in ft/sec) after t seconds (see accompanying figure) is given by

v ( t ) = 80 + 10 t e − t / 4 ( 0 ≤ t ≤ 30 ) .
