A 60 kg skydiver is falling at a terminal velocity of 50 m/s.

calculate the amount of gravitational force acting on the skydiver.

Is it possible to use the energy from two atoms colliding to create a clean burning lasting fuel source with a large amount of force? is it also possible to harness that energy from the two atoms colliding to create a clean energy source that will last for years from just two atoms colliding. is there a possibility to control and store that energy for years but slowly let the energy out enough to power cities cheaper and faster.
