A hockey puck is hit so that it moves along the nearly frictionless ice at $20\mathrm{m}/\mathrm{s}$. How long will it take to travel $10\mathrm{m}$ ? The same hockey puck is hit so that it flies into the air. If it hits the ice $10\mathrm{m}$ away from where it was hit and takes the same time to get there, what was the highest distance it was off the ice?
