[SOLVED] Velocity of a car skidding
A 2.20 103 kg car rounds a circular turn of radius 30.0 m. If the road is flat and the coefficient of static friction between the tires and the road is 0.8, how fast can the car go without skidding?
Fcentripital=ma
a=v2/t
v=2πr/t
So i used F=ma and substituted F with Coefficient*mass*gravity and for ma i used
m 2πr/t and solved for t. Then i used the t for the velocity equation and solved it. I got 24.0 m/s but it was wrong. What did i do wrong?
