1. The problem statement, all variables and given/known data A 1.00 x10^3 kg car is moving through a flat curve on a road at a velocity of 30.0 m/s. If the coefficient of friction between the road and the tires is 0.600, the radius of the curve is 2. Relevant equations r=v^2/(coefficitent of friction)(g), r=mv^2/F 3. The attempt at a solution I tried two ways so solve this question, but im not sure which was is correct. the first thing i did was, find F by multiplying 9.81m/s2 and the mass (1000). then plugging that into the r=v^2/f. Then i used the first formula i provided above and just plugged all the variables in (excluding mass). Does the mass need to somehow be in there?
In [itex]r = mv^2/F[/itex], the force should be the centripetal force that holds the car in the curve, not the weight of the car.
