EASY speed of curve PROBLEM!!!!
A race track curve has a radius of 100 m and is banked at an angle of 68 degrees. For what speed was the curve designed?
ok this is what i got since tan angle = v^2/rg i got tan 68 = v^2/rg so tan 68 x rg = v^2 but this gave me an answer far from the actual answer of 49. please help! |

[tex]v=\sqrt{980\tan68^\circ}\approx49.25[/tex]
