A box of mass 25 kg starts from rest and slide down as inclined plane 8 metre long and 5 meter length . It is found to move at the bottom at 7 m//s . What is the force of friction?

A box of mass 25 kg starts from rest and slides down an inclined plane 8 meter long and 5 meter high. It is found to move at the bottom at 7 m/s. What is the force of friction

A body of mass 50 kg starts from rest and slides down a smooth incilined plane. Find the force ..p.. applied at an angle 30^(@) to the inclined plane so that the body attains a velocity of 10ms^(-1) after sliding a distance of 7m.

A block of mas m begins to slide down on an inclined plane of inclination theta . The force of friction will be

Starting from rest , a body slides down at 45^(@) inclined plane in twice the time it takes to slide down the same distance in the absence of friction. The coefficient of friction between the body and the inclined plane is
