A skydiver jumps from an airplane, the resistance he encountered is proportional to its velocity and his limiting velocity is equal to 10 fps. After 20 minutes, he opens his parachute, at that moment the resistance increases thrice to it original velocity. If he landed after 35 minutes, what is the altitude of the plane the moment the skydiver jumps from it? Assume its second limiting velocity is 4fps.

Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.
