A smooth inclined plane is set up on a laboratory bench. The angle of inclination is measured with a protractor as 5.0°. A steel ball is released from rest at the top of the plane and allowed to roll down without slipping. The distances (s) from the start point and the corresponding times (t) taken for the ball to reach each mark are recorded as follows: | s (m) | t (s) | |-------|-------| | 0.20 | 0.64 | | 0.40 | 0.90 | | 0.60 | 1.12 | | 0.80 | 1.30 | Using the data provided, answer the following:

( a )

Calculate the average acceleration of the ball from the data. (Hint: use the relation s = ½ a t²).

( b )

Determine the theoretical acceleration of the ball down the incline using g = 9.81 m s⁻² and the measured angle.

( c )

Calculate the percentage error between the experimental and theoretical accelerations.

( d )

Suggest two possible sources of error that could affect the results and briefly explain how each would influence the measured acceleration.
