An airplane is flying with a speed of 285 km/h at a height of 3500 m above the ground. A parachutist whose mass is 77.6 kg, jumps out of the airplane, opens the parachute immediately and then lands on the ground with a speed of 3.45 m/s. How much energy was dissipated on the parachute by the air friction? The drag constant of the parachute is 64.0 N/(m/s)^2.
I assume you find the total energy lost but I dont know what to do from there
