A parachutist with a mass of 50.0 kg jumps out of an airplane with an altitude of 1.00 x 10^3 m. After the parachute deploys, the parachutist lands with a velocity of 5.00 m/s. Find the energy that was lost to air resistance during th jump.
I tried using this: W = Kf – Ki → W = ½ mv^2 (f) – ½ mv^2 (i)
but I don't know what the initial velocity was because I don't know when the parachute deploys. How do you solve this problem?
