Question 2

A car turns at a constant speed on a circular track of radius 100 m, taking 62.8 s for every circular loop. The average velocity and average speed for each circular loop respectively is :

Question 3

If the centripetal force on a car of mass 150 kg in a circular road is 300 N. find the banked angle of road. Assume that the

Question 4

A particle of mass 10 g moves along a circle of radius 6.4 cm with a constant tangential acceleration. What is the magnitude of this acceleration, if the kinetic energy of the particle becomes equal to 8 x 10-4J by the end of the second revolution after the beginning of the motion?

Question 5

If a car is travelling on a banked circular road with velocity 100 m/s. The angle of banking is 30◦. Mass of the car is 1000 kg. Find the approximate frictional coefficient between car and road such that car does not skid. The radius of curvature is 500 m.
