Question

Supposed a skydiver ( mass=75kg ) is falling toward the earth. When the skydiver is 100m above the earth he is moving at 60m/s. At this point calculate the skydiver: Gravitational potential energy
Kinetic energy
Total mechanical energy

Answer 1

gpe: mass*g*height
KE: 1/2 mass*velocity^2
total ME: add the above

Answer 2
