Question

Surprsingly, very few athletes can jump more than 2 feet (0.6m) straight up. Use d=1/2gt squared and solve for the time one spends moving upward in a 0.6-m vertical jump. Then double it for the "hang time" -the time one's feet are off the ground.

Step 1

The time the athlete spends moving upwards is,

Step 2

The hang tim...
