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=? [gsin10 -- but why?????]

2. Relevant equations

V^2=Vo^2 +2ax

3. The attempt at a solution

okay...i dont understand why a=gsin(10) [g=9.8]

because from the triangle i draw ..g is not the hypotenuse? im confused to see WHY a=9.8sin(10).
