1. The problem statement, all variables and given/known data[/b] A car is rolling down a ramp that is inclined at and angle of 9.9 degree with respect to horizontal. There is no friction acting from the road on the tires. Employ conservation of mechanical energy to find the speed of a car that starts from rest and rolls down the ramp a distance of 52 m. 2. Relevant equations[/b] 1/2mv(initial)^2+mgh(initial)=1/2mv(final)^2+mgh(final) 3. The attempt at a solution[/b] Vi=0m/s Vf=? hi=52m hf=0 52mg=1/2vf 2*52m*9.81m/s^2=vf √1020.24m^2s^2=√v 31.94m/s=v I got a 1 out of ten in this problem. most likely got the units right, but my math did I used the right equation?
