Question

3.
For a curved track of radius R, banked at angle 0
(A) a vehicle moving with a speed Vo = VRg tan 0 is able to negotiate the curve without calling
%3D
friction into play at all.
(B) a vehicle moving with any speed V > Vo is able to negotiate the curve, with friction called into
play.
(C) a vehicle moving with any speed V< Vg must also have the force of friction into play.
(D) the minimum value of the angle of blanking for a vehicle parked on the blanked road can stay
there without slipping, is given by 0 = tan H. (H = coefficient of static friction)
