Use any means at your disposal (including the internet) to justify estimates of the following: 

(a) The kinetic energy of the Moon in its motion around Earth. 

(b) The kinetic energy of a raindrop before it hits the ground. 

(c) The potential energy of the water in Lake Powell (relative to the level of the Colorado river directly beneath the dam). 

(d) Energy needed for you to power a bicycle 15 km at 15 km/h on flat terrain.

(e) The energy lost to air resistance by an Olympic athlete running a 100 m race. 

(f) The gravitational potential energy of a climber at the top of Mount Everest.
