A low‑friction air‑track is set up to investigate uniformly accelerated motion of a glider. The track is inclined at an angle of 5.0° to the horizontal. The glider is released from rest at the top and the time taken to travel successive 0.20 m intervals is recorded in the table below. | Distance travelled, s (m) | Time taken, t (s) | |---------------------------|-------------------| | 0.20 | 0.64 | | 0.40 | 0.90 | | 0.60 | 1.12 | | 0.80 | 1.31 | | 1.00 | 1.48 | Using this data, answer the questions that follow.

Question Parts

( a )
Plot s (m) against t² (s²) and determine the experimental acceleration of the glider.
( b )
Theoretically, the acceleration of a body down an incline is a = g sinθ. Calculate the theoretical acceleration for the given angle.
( c )
Determine the percentage error between the experimental and theoretical accelerations.
( d )
State two possible sources of error that could have caused the experimental acceleration to be higher than the theoretical value.
