How much work done in pulling up a block of wood weighing 2kN for length of 10 m on smooth incline plane at angle 15^(@) with horizontal ?

The work done in moving a body of mass 5kg from the bottom of a smooth inclined plane to the top is 50 j. If the angle of inclination of the inclined plane is 30^(@) , its length is (g = 10 ms^(-2))

The time taken by a block of wood (initially at rest) to slide down a smooth inclined plane 9.8 m long (angle of inclination is 30^(@) ) is

The time taken by a block of wood (initially at rest) to slide down a smooth inclined plane 9.8 m long (angle of inclination is 30^(@) ) is

A person pushes a block of mass 4 kg up a frictionless inclined plane 10 m long and that makes an angle of 30^@ with the horizontal . Then the work done is
