A body is sliding down an inclined plane having coefficient of friction 0.5. If the normal reaction is twice that of the resultant downward force along the inclined plane , then find the angle between the inclined plane and the horizontal.

Find the acceleration of a body falling down a rough plane, inclined at an angle 30^@ . The force of friction is 0.2 times the normal reaction. After descending 1m along the inclined plane, what will be the change in the sum of the potential and the kinetic energies ? Mass o the body is 1g.

An object of mass 10 kg is falling down along an inlcined plane of angle 30^@ . If coefficient of friction 0.25 , then calculate acceleration towards down.

A block of mass M rests on an inclined plane. If the coefficient of friction between the block and the plane is mu , then the block will slide down the plane under its own weight when the angle of inclination is

A particle is sliding down along an inclined plane. Frictional force is 0.2 times the normal reaction , and the inclination of the plane is 60^@ . What is the acceleration of the particle ? If the mass of the particle is 1g , find the change in the sum of potential and kinetic energies of the particle as it slides down the plane by 1 m.

A block of mass M rests on an inclined plane. If the coefficient of friction between the block and the plane is mu then the block will slide down the plane under its own weight the angle of inclination is

A body is sliding down an inclined plane of inclination theta with a uniform velocity. If the body is projected with a velocity u along the plane upwards, show that it will ascend a distance u^2//4g sin theta along the plane.
