Champion ridget hurler Chuck Fahr throws a ridget with an upward velocity of 50 meters/second. If the height of the ridget is expressed as

h = 5000(1 – e–t/20) – 200t

In this equation, h is the height in meters and t is the time in seconds. The desired solution is the positive value of t at which h = 0.
