A hockey puck sliding on a frozen lake comes to rest after traveling 175m. If it's initial velocity is 1.0m/s, what is its acceleration if that acceleration is assumed constatnt? Answer in units of m/s^2 I first divided 175/1.9 to get 92.11s. I then put 1.9/92.11 to get 0.02063. But it's wrong. Any ideas? Thanks.
