A 100 kg box slides without acceleration down a rough inclined plane making an angle of `30^0` with the horizontal. Find it’s acceleration when the inclination of the plane is increased to `60^@`.

A body slides down on a rough inclined surface making an angle of 60^@ with the horizontal. Find its acceleration if mu=0.2 .

A 50 gm box is placed on an inclined plane making an angle of 30^@ with the horizontal so that a gentle tapping causes the sliding of the box. Calculate the coefficient of static friction for the surfaces of the box and the inclined plane in contact.

A thin circular ring rolls down a smooth inclined plane of inclination 30degree without slipping. What is it's linear acceleration in the plane ?

A box is placed on an inclined plane and has to be pushed down. The angle of inclination

A block slides down an incline of an 30^@ with an acceleration of g/4 Find the coefficient of kinetic friction.

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

A jeep moving at a speed of 50 km/hr reaches the foot of smooth incline where its engine is switched off. How much distance does the jeep go up the incline before coming to rest ? The inclination of the plane to the horizontal is 45^@ and the acceleration due to gravity at the place is 9.8m/s^2

A body moving with uniform acceleration has velocity of 20m/s and 30 m/s when passing point P with Q in its path . Find its velocity at the point midway between P and Q .
