A cyclist allows his bike to roll down a hill without pedaling. Towards the bottom of the hill he applies his brakes. The bike comes to a stop. Applying the brakes causes the brakes to warm up. Describe the energy transfers that have occurred.

An object is placed in a fluid and then released. Assume that the object either floats to the surface (settling so that the object is partly above and partly below the fluid surface) or sinks to the bottom.
