Question 5 WAEC_MODEL_QUESTIONS_VOL1 • 2020 • 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 distance of 5.0 m along the plane. The coefficient of kinetic friction between the block and the plane is 0.20. At the bottom of the incline the block contacts a horizontal spring of force constant 400 N m⁻¹ and compresses it. Neglect air resistance.

Question Parts

( a )
Calculate the work done by gravity on the block during its descent.
( b )
Calculate the work done by friction during the descent.
( c )
Find the speed of the block just before it contacts the spring.
( d )
Determine the maximum compression of the spring.
