Circular Travelling

A car starts rest, on a horizontal circular road of radius R, the tangential acceleration of the car is a. The friction coefficient between the road and the tyre is mu Find the speed at which car will skid and also find the distance after travelling it skids.

Why are the passengers thrown outwards when a car in which they are travelling suddenly takes a circular turn?

A particle starts travelling on a circle with constant tangential acceleration. The angle between velocity vector and acceleration vector, at the moment when particle completes half the circular track. Is

A car of mass 840 kg moves on a circular path with constant speed of 10 m//s . It is turned through 90^@ after travelling 660 m on the road. The centripetal force acting on the car is

A car of mass 1000kg moves on a circular path with constant speed of 12 m//s . It turned through 90^@ after travelling 471 m on the road . The centripetal force acting on the car is

A car of mass 1000 kg moves on a circular path with constant speed of 16 m/s. It is turned by 90º after travelling 628 m on the road. The centripetal force acting on the car is-

A current flows in a wire of circular cross section with the free electrons travelling with drift velocity vecV . If an equal current flows in a wire of twice the radius, new drift velocity is

The current i flows in a wire of circular cross-section with the free electrons travelling with a drift velocity v. What is the drift velocity of electrons when a current of 2 i flows in another wire of twice the radius and of the same material ?

The radius of a circular wheel is 1""(3)/4m . How many revolutions will it make in travelling 11km ?
