Question

Suppose you are playing ice hockey in the middle of a totally frictionless frozen pond? How can you move yourself to the edge of the pond? Remember that without friction, you won't be able to push against the ice. Explain what you would do and why it would work.

Answer 1

if it is totally frictionless you can only need to throw the hockey stick to one other side and wait for yourself to move slowly to the other side. this will happen by the law of conservation of momentum and Newton's First law (continues to move in the uniform velocity without external I. e. friction, Force).
