A 55.0-kg skydiver free falls for a period of time before opening his parachute. What is his kinetic energy when he reaches a velocity of 16.0 meters/second?

Good grief. Enough, already. Do the calculation yourself. The equation has already been provided.

• physics -

use 1/2mv^2
(1/2)(55)(16)^2=7040 J
