Question 4 NECO • 2018 • PHYSICS • practical

A wooden block of mass 0.80 kg rests on a horizontal wooden table. The block is attached to a light string that passes over a smooth pulley and is connected to a spring balance. Masses are added to the hanging end of the string until the block just begins to move. The spring balance reading at the instant of impending motion is 3.2 N. The coefficient of static friction between the block and the table is to be determined and used to predict the force required if the block's mass is increased by 0.50 kg.

Question Parts

( a )

State the reading on the spring balance when the block just starts to move.

( b )

Calculate the coefficient of static friction (μ_s) between the block and the table.

( c )

If the mass of the block is increased to 1.30 kg, predict the new spring‑balance reading required to start the block moving, assuming the same coefficient of static friction.

( d )

List two possible sources of error in this experiment and suggest one method to reduce each error.
