1. The problem statement, all variables and given/known data A skier is gliding along at 3m/s on horizontal frictionless snow. He suddenly starts down a 10 degree incline. His speed at the bottom is 15 m/s. a) what is the length of the incline? b) how long does it take for him to reach the bottom? we know: Vo=3m/s Vf=15m/s t=? x=? a=? 2. Relevant equations V^2=Vo^2 +2ax 3. The attempt at a solution i need help to find what the a is...and why it is that.
