Homework Statement
A car with mass 1200kg rounds a curve banked at 18 degrees. The radius of the curve is 130 m.
Find the speed of the car if the frictional force between the tires and the road is 3.5 x 10^3 down the banked curve.
Homework Equations
ac = v2/r
The Attempt at a Solution
After breaking it up into x and y components, I came up with the following:
v = sqrt((rFgtanx + Fktanxsinx + Fkcosx)/m)
Solving for it, I got about 20 m/s. The answer is 29 m/s. I think I just made some sort of calculating error or missed a negative, but I haven't been able to find it. Any help?
