Question 3 NECO_MODEL_QUESTIONS_VOL1 • 2018 • PHYSICS • practical

A student sets up an inclined plane of length 2.00 m. The vertical height of the plane is measured as 0.60 m. A cart of mass 0.500 kg is released from rest at the top and allowed to travel the whole length. The time taken for the cart to reach the bottom is recorded with a stop‑watch for three trials: 1.85 s, 1.78 s and 1.82 s. Air resistance is negligible and the motion is assumed to be uniformly accelerated.

Question Parts

( a )

Calculate the average speed of the cart over the inclined plane.

( b )

Assuming the cart moves with constant acceleration, determine the experimental value of the acceleration.

( c )

Determine the angle of inclination of the plane.

( d )

Calculate the theoretical acceleration down the plane (g sin θ) and compare it with the experimental value obtained in part (b). State at least two possible sources of error that could account for any discrepancy.
