Question

previous 12 of 12 retun Banked Frictionless Curve, and Flat Curve with riction Part A What is the radius r of the turn if -20.0% (assuming the car continues in uniform circular motion around the turn)? A car of mass M = 1400 kg traveling at 50.0 km/hour enters a banked turn covered with ice. The road is banked at an angle and there is no friction between the road and the car's tires as shown in (Figure 1). Use g 9.80 m/s throughout this problem Express your answer in meters. Hints Submit My Answers Give Up Part B This question will be shown after you complete previous question(s). Provide Feedback Conti Figure 1 of 1 0/

Explanation / Answer

The velocity in frictionless banked roads is given by:

v = sqrt(r*g*tan(angle))

v = 50 Km/hour = 13.99 m/sec

angle = 20 degress

g = 9.8 m/sec^2

r = v^2/g*tan(angle) = 54.87 m
