The problem:
A car is traveling along a curve having a radius of 74.0m, banked at an angle of theta = 23 deg. The coefficient of static friction is 0.09. What is the slowest speed the car can negotiate the curve?
Relevant equations:
Fc = Fnet
Fc = mv^2/r
Fnet = [(tan(theta) + u)/(1-utan(theta))]mg
The attempt at a solution
v^2 = (74)[(tan23 + 0.09)/(1-0.09tan23)](9.8)
v = (387.92)^0.5
v= 19.70 m/s
This answer isn't being accepted by the online program we use in class and I can't figure out what I'm doing wrong. Any help would be much appreciate
