Question 5 NECO • 2022 • PHYSICS • essay

A block of mass 10 kg rests on a rough inclined plane that makes an angle of 30° with the horizontal. The coefficient of kinetic friction between the block and the plane is 0.20. The block is pulled up the plane to the top, a distance of 5.0 m, by a constant force of 80 N acting at an angle of 20° above the plane. The diagram of the situation is provided.

( a )

Calculate the work done by the applied force during the displacement.

( b )

Determine the work done against friction over the same displacement.

( c )

Find the net work done on the block.

( d )

If the block starts from rest, calculate its speed at the top of the incline.
