A body is in limiting equilibrium on a rough inclined plane inclined at an angle of `30^@` with the horizontal. Calculate acceleration with which the body will slide down, when inclination of the plane is changed to `45^@`. Given `g=9.8m s^(-2)`.

A block is in limiting equilibrium on an inclined plane of angle theeta ,Then ,the coefficient of friction is :

An inclined plane makes angle of 30^@ with horizontal.A solid sphere rolls down this inclined plane from rest without slipping .the acceleration of the sphere is :

When a body slides down from rest along a smooth inclined plane making anangle of 45^@ with the horizontal, it takes time T. when the same body slides down from rest along a rough inclined plane making the same angle and through the same distance, it is seen to take time pT, where p is some number greater than 1. Calculate the co-efficient of friction between the body and the rough plane.

A cubical block rests on an inclined plane with four edges horizontal.If mu = 1/sqrt3 determine the angle when the block just slides down the plane.

A wire of mass 9.8*10^(-3) kg per metre passes over a friction less pulley fixed on the top of an inclined friction less plane which makes an angle of 30^@ with the horizontal. Masses M_(1) and M_(2) are tied at the two end of the wire. The mass M_(1) rests on the plane and the mass M_(2) hangs vertically downward. The whole system is in equilibrium. Now a transverse wave propagates along the wire with a velocity of 100ms^(-1) . Find the values of masses M_(1) and M_(2) . Take g= 9.8ms^(-2) .

A body weighing 20 kg just slides down a rough inclined plane that rises 5 m in every 12 m.What is the coefficeint of friction?

A body of mass 5 kg placed on the surface of rough inclined plane rising 7 in 25 just slides down. Calculate the value of limiting friction ci-efficient of friction.

A mass of 4 kg rests on a horizontal plane. The plane is gradually inclined at an angle theta = 15^@ with the horizontal, the mass just begins to slide. What is the coefficient of static friction between the block and the surface?

A car of mass 1000 kg starts from rest and comes down an inclined slope. If it travels a distance of 300 m in 30 seconds, calculate acceleration
