1. (4 POINTS) Hang Time. One of the most exciting plays in basketball is the dunk shot. The amount of time T that passes from the moment a player leaves the ground, goes up, makes the shot, and arrives back on the ground is called the hang time. A function relating an athlete’s vertical leap V, in inches, to hang time T, in seconds, is given by [pic] a. Carl Landry, of Purdue University, has a hang time of about 0.835 sec. What is his vertical leap? V (0.835) = 48(0.835^2) = 33.47 seconds

b. The record for the greatest vertical leap in the NBA is held by Darryl Griffith of the Utah Jazz. It was 48 in. What was his hang time? T^2 = V/48 T^2 = 48/48 = 1 T = 1 second

2. (4 POINTS) Falling Distance. An object that is tossed downward with an initial speed (velocity) of [pic]will travel a distance of s meters, where [pic] and t is measured in seconds. Solve for t.

s = 4.9t^2 + v0 t 4.9t^2 + v0 t - s = 0 x = [-b ± √ (b^2 - 4ac)] / 2a= t = [-v0 ± √ {(v0) ^2 - 4 * 4.9 * -s}] / (2 * 4.9) t = [-v0 ± √ {(v0) ^2 + 19.6s}] / 9.8
