A road is properly banked for a car travelling at 60km/hr, how much friction is needed for a car going at 90km/hr? (time sensitive...10 minutes)

Do you either the radius of the circle or the angle of the incline? I can't solve for it if I am missing one.

because the time is in minute, lets convert the velocity to km/minute so v1=1km/min v2 = 1.5km/min the friction needed will be f=m.a the velocity's difference is 0.5 so a=0.5/10 = 0.05km/min^2 friction needed = m x 0.05 CMIIW
