Question 5.5 · May/June 2023 · Paper 1 · National (DBE) · 4 marks

An electric motor pulls a kg crate from rest at point A up an inclined plane by means of a light inextensible rope. The inclined plane makes an angle of with the horizontal. B, C and D are points on the inclined plane and the distance between points A and C is m, as shown in the diagram below.

The motor exerts a constant force of N parallel to the inclined plane on the rope.

A constant frictional force of N acts on the crate as it moves on the inclined plane.Diagram for this question
5.5 Draw a velocity-time graph for the entire motion of the crate starting from point A until it passes point B again on its motion down the inclined plane.(4)
