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.

You have your bicycle upside down while you adjust the chain. The chain is wound around the rear wheels small gear, which has a radius of 4.0 cm. At the pedals, the chain is wound around the large gear, which has a radius of 11.0 cm. The radius of the rear wheel is 35.0 cm. You spin the pedals initially so they finish two revolutions in 1.0 s, starting from rest. Assume constant acceleration. (a) Find the angular acceleration of the rear wheel in rad/s2. (b) Find the magnitude of the total acceleration of a point at the edge of the small gear at the end of 1.5 s (the sum of the radial and tangential accelerations). (c) What is the tangential acceleration for that point during the first second? (d) Calculate the linear acceleration of the chain.
