Question
A highway curve with radius 1000ft is to be banked so that a car traveling 56.0mph will not skid sideways even in the absence of friction
At what angle should the curve be banked?
At what angle should the curve be banked?
Answers
horizontal component of g = v^2/r
g sin theta = v^2/r
here g = 32 ft/s^2
v = 56 mi/h * 5280 ft/mi * 1 h/3600 s
r = 1000 ft
g sin theta = v^2/r
here g = 32 ft/s^2
v = 56 mi/h * 5280 ft/mi * 1 h/3600 s
r = 1000 ft
