A train runs along an unbanked circular bend of radius 30 m at a speed of 54 kmh–1. What is the angle of banking required to prevent wearing out of the rail ? (g = 10 ms–2)A 53° B 45° C 60° D 37°

A car goes along the circular curve of radius 30 m. If the road is banked at an angle of015 withthe horizontal, calculate the maximum speed in m/s at which the car can travel without skid.

5.1 Uniform Circular MotionAt what angle (relative to the horizontal) should a curve 52 m in radius be banked if no friction is required to prevent the car from slipping when traveling at 10 m/s? (g = 9.8 m/s2)Select one:a.32°b.28°c.11°d.16°

A race car track has been constructed with the a bank angle of 32.2° so there is no friction force. The race car track has a curve radius of 360. m. What speeds, for the race cars, has the track been designed to accommodate? 15.1 m/s 47.1 m/s 2.22×103 m/s 54.6 m/s

A highway curve has a radius of 817 m. At what angle should the road be banked so that a car traveling at 27.0 m/s (60.4 mph) has no tendency to skid sideways on the road?

A highway is being constructed to accommodate traffic for speeds of 12.2 m/s. If the angle of the bank is 7.97° and there is no friction force, what is the highway's curve radius? 1.06×103 m 8.89 m 15.3 m 108 mQuestion 2A girl with a 59.4 g yo-yo is swinging it in a horizontal circle at an angular velocity of 7.86 rad/s. If the string is tilted down at an angle of 25.1°, what must the length of the yo-yo string be? 0.0222 m 0.0382 m 0.374 m 0.175 mQuestion 3A 2.50 kg toy race car is slowing down while travelling around a circular horizontal track. If the track has a diameter of 1.73 m and the coefficient of rolling friction between the track and the race car is 0.280, what is the magnitude of angular acceleration? 0.324 rads/s2 1.59 rads/s2 3.17 rads/s2 0.162 rads/s2
