Question 5 NECO_MODEL_QUESTIONS_VOL1 • 2023 • PHYSICS • essay

A 50 kg crate is pulled up a rough inclined plane that is 10 m long and makes an angle of 30° with the horizontal. The pulling force is a constant horizontal force of 400 N. The coefficient of kinetic friction between the crate and the plane is 0.20. The crate starts from rest at the bottom of the plane and moves to the top.

Question Parts

( a )

Calculate the work done by the horizontal pulling force during the ascent.

( b )

Determine the work done by the kinetic friction force during the ascent.

( c )

Find the net work done on the crate and its speed when it reaches the top of the plane.

( d )

Calculate the magnitude of the constant acceleration of the crate while it moves up the plane.

( e )

If the crate reaches the top in the time found from the acceleration, determine the average power supplied by the horizontal pulling force during the ascent.
