This problem I have to do is really bothering me. Your 1600 kg PT Cruiser moves around a level 50m radius road. The coefficient of STATIC friction between the car tires and the road is 0.80. Determine the MAX speed of the car so that it does not skid off the road. I think I get somewhere around. ma - mg*0.80 = mv^2 / R I'm sure this is wrong because m shouldn't be able to be cancelled. Always ALL the information provided is used in the calculation.
