A smooth inclined plane of length 2.00 m is set at an angle of 30° to the horizontal. A steel ball is released from rest at the top and allowed to roll down the plane. Using a digital timer, the time taken for the ball to travel three successive distances measured from the top was recorded as shown in the table. | Distance from top (m) | Trial 1 (s) | Trial 2 (s) | Trial 3 (s) | |-----------------------|------------|------------|------------| | 0.50 | 0.62 | 0.64 | 0.63 | | 1.00 | 0.88 | 0.90 | 0.89 | | 1.50 | 1.10 | 1.12 | 1.11 | Assume the ball starts from rest at each measured point (u = 0).

Question Parts

( a )
Calculate the average time for each distance.
( b )
Using s = ½ a t² (u = 0), determine the acceleration of the ball for each distance and then obtain the average experimental acceleration.
( c )
Calculate the theoretical acceleration down the plane using g = 9.81 m s⁻² and the given angle. Then compute the percentage error of the experimental value obtained in part (b).
( d )
State two possible sources of error in this experiment and suggest a practical way to minimise each.
