I need some help, I am a relative noob at physics. I need this to get credit on test corrections to boost my test grade. Here's the problem, A 1300 kg car goes around a turn with radius 50 m, at a speed of 75 km/h. The coefficient of static friction is .45, (a) what is the minimum angle of the bank needed to keep the car in the turn? (b) If the car changes tires, which increase the coefficient of static friction to .65, what will be the maximum velocity with which the car will be able to take the turn, assuming the same banked angle? This is probably easy for you guys. Any help would be appreciated, Thanks.
