My freakin' physics weakness is back~
Question: A civil engineer wishes to design a curved exit ramp for a highway in such a way that a car will not have to rely on friction to round the curve without skidding. In other words, a car moving at the designated speed can negotiate the curve even when the road is covered with ice. Such a ramp is usually banked: this means the roadway is tilted toward the inside of the curve. Suppose the designated speed for the ramp is to be 13.4m/s (30.9 mi/h) and the radius of the curve is 50.0m. At what angle should the curve be banked?

anonymous · Answer

Radius of turn = 50 m
Speed = 13.4 m/s
Vertical acceleration = g
Angle = ?
