You find yourself trapped in the middle of a large frozen lake. Assume the ice has no friction. All you have on your is warm winter clothing and no way to call/signal for help. You can just barely see the shore in the distance. Use your physics knowledge of Newton's laws to help get you off the lake. Explain your reasoning.
