A block is projected upwards on a rough inclined plane at 20 m/s. let the time in going up, then is equal to

A block is pushed up a rough inclined plane of 45^(@) .If the time of descent is three times the time of ascent,the coefficient of friction is ?

A block of mass m is placed on a rough inclined plane. When the inclination of the plane is theta , the block just beging to slide down the plane under its own weight. The minimum force applied parallel to the plane, to move the block up the plane, is.

A block is pushed up a rough inclined plane of 45°. If the time of descent is twice the time of ascent, the coefficient of friction is

A body is projected up along the rough inclined plane from the bottom with some velocity. It travels up the incline and then returns back. If the time of ascent is t_(a) and time of descent is t_(d) then
