At the base of a frictionless icy hill that rises at 29.0deg above the horizontal, a toboggan has a speed of 12.0 m/s toward the hill. How high vertically above the base will it go before stopping?
Homework Equations
Wtot=K2-K1
K=1/2mv^2
K2=1/2mv^2=K1+Wtot
The Attempt at a Solution
Vx=12cos(29) = 10.5 m/s
vf^2-vi^2=2as
0-(10.5)^2=2(-9.8)s
s= 5.625
