Topic: Forces

Question 4 NECO • 2022 • PHYSICS • essay

A 10 kg crate is pulled up a smooth inclined plane that makes an angle of 20° with the horizontal. The pulling force of magnitude 80 N is applied in a direction 30° above the horizontal. The coefficient of kinetic friction between the crate and the plane is 0.15.

Question Parts

( a )

Resolve the pulling force into components parallel and perpendicular to the plane and state their numerical values (to two decimal places).

( b )

Determine the normal reaction exerted by the plane on the crate.

( c )

Calculate the kinetic friction force acting on the crate.

( d )

Find the net force parallel to the plane, the resulting acceleration of the crate, and the work done by the pulling force after the crate has moved 5.0 m up the plane.
