Question 1 NECO • 2020 • PHYSICS • essay

A laboratory experiment is to be carried out to determine the coefficient of kinetic friction (µk) between a wooden block and an inclined plane using a hanging mass and a protractor. The block has a mass of 0.50 kg and is placed on the plane. A string connects the block to a hanging mass of 0.20 kg that passes over a smooth pulley at the top of the plane. The angle of inclination of the plane is set to 30°. The system is allowed to move at constant speed when the hanging mass is released. Assume g = 9.8 m s⁻² and the pulley is frictionless.

( a )

State the purpose of the experiment.

( b )

List all the apparatus required for the experiment.

( c )

Describe briefly the procedure to be followed.

( d )

Using the data given, calculate the coefficient of kinetic friction (µk) between the block and the plane. Show all steps.
