Question

A civil engineer wishes to redesign a curved roadway in such a waythat a car will not have to rely on friction to round the curvewithout skidding. In other words, a car moving at the designatedspeed can negotiate the curve even when the road is covered withice. Such a ramp is usually banked, meaning the roadway istilted toward the inside of the curve. Suppose the designated speedfor the ramp is to be 14.4 m/s(32.2 mi/h) and the radius of the curve is36 m.

a.For the above example, suppose that the coefficient of staticfriction between the tires and the road is 0.37. What maximum speed could a car negotiate theexit ramp without skidding?
