Question 5 NECO • 2024 • PHYSICS • essay

A 5.0 kg block is released from rest at the top of an inclined plane that makes an angle of 30° with the horizontal. The smooth part of the incline is 4.0 m long, after which the surface becomes rough for a further 2.0 m. The coefficient of kinetic friction on the rough section is 0.20. At the bottom of the rough section the block compresses a horizontal spring of spring constant 800 N·m⁻¹ until it momentarily comes to rest.

( a )

Determine the speed of the block at the point where the smooth part ends and the rough part begins.

( b )

Calculate the work done by the kinetic friction force on the block while it travels the rough 2.0 m section.

( c )

Using the speed found in part (a) and the work of friction from part (b), determine the maximum compression of the spring.
