A student investigates the motion of a marble down a smooth wooden ramp. The ramp length is 1.20 m. The ramp can be set at different angles. For each angle the marble is released from rest at the top and the time taken to travel the whole length is measured with a stopwatch. The recorded times are:

Question Parts

( a )
Calculate the linear acceleration of the marble for each angle (15°, 30°, 45°). Use the equation s = ½ a t² where s = 1.20 m.
( b )
Using the accelerations obtained, comment on whether the acceleration is proportional to sin θ. Show the reasoning with appropriate calculations.
( c )
Suggest two practical improvements that could reduce the discrepancy observed in part (b).
