A body of mass 10 kg is sliding down a rough inclined plane which makes an angle of `30^@` with the horizontal. If the coefficient of friction is 0.25, what is the acceleration of the body ?

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 :

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.

In the figure, a body A of mass m slides on plane inclined at angle theta_1 to the horizontal and mu_1 is the coefficient of friction between A and the plane. A is connected by a light string passing over a fictionless pulley to another body B, also of mass m, sliding on a frictionless plane inclined at angle theta_2 to the horizontal which of the following statements are true ?

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 cylinder of mass 10 kg and radius 15 cm is rolling perfectly on a plane of inclination 30^@ . The co-efficient of static friction mus = 0.25 :- How much is the force of friction acting on the cylinder ?

A cylinder of mass 10 kg and radius 15 cm is rolling perfectly on a plane of inclination 30^@ . The co-efficient of static friction mus = 0.25 :- If the inclination theta of the plane is increased, at what value of theta does the cylinder begin to skid, and not roll perfectly ?

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 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?
