Question 5 WAEC_MODEL_QUESTIONS_VOL1 • 2024 • PHYSICS • essay

A smooth inclined plane makes an angle of 30° with the horizontal. A 2.0 kg block is released from rest at the top of the plane and slides down a length of 10.0 m to the bottom. The coefficient of kinetic friction between the block and the plane is 0.20. Take g = 9.8 m s⁻². Answer the following:

Question Parts

( a )

Determine the magnitude of the block’s acceleration down the plane.

( b )

Find the speed of the block after it has travelled 5.0 m down the plane.

( c )

Calculate (i) the work done by friction, (ii) the work done by gravity over the whole 10.0 m descent, (iii) the net work on the block, and (iv) the average power delivered to the block during its motion.
