A64 kg sky diver jumped out of an airplane at an altitude of 0.90 km. she opened her parachute after a while and eventually landed on the ground with a speed of 5.8 m/s. how much energy was dissipated by air resistance during the jump?

563403.5 J

Explanation:

= mass of the skydiver = 64 kg

= Altitude of the airplane = 0.90 km = 900 m

= speed at the time of landing = 5.8 m/s

Gravitational potential energy of the skydiver at the airplane is given as

Kinetic energy of the skydiver at the time of landing is given as

= Energy dissipated by air resistance

Energy dissipated by air resistance during the jump is given as

what is the actual question though?
