A penguin stands at the left edge of a uniform sled of length L, which lies on frictionless ice. The sled and the penguin have equal masses. (a) Where is the center of mass of the sled? (b) How and in what direction is the center of mass of the sled from the center of mass of the sled-penguin system? The penguin then waddles to the right edge of the sled and the sled sides on the ice. (c) Does the center of mass of the sled-penguin system move leftward, rightward, or not at all? (d) Now how far and in what direction is the center of the sled from the center of mass of the sled-penguin system? (e) How far does the penguin move relative to the sled? Relative to the center of mass of the sled-penguin system, how far does (f) the center of the sled move and (g) the penguin move?

2. Relevant equations

None other than concept COM ideas.

3. The attempt at a solution

(a)The center of mass for the less is obviously in the center.

(b) The COM for sled is L/2 right from the COM for sled-penguin system.

IDK how to do the rest.
