Question 3 NECO_MODEL_QUESTIONS_VOL1 • 2024 • PHYSICS • practical

A low‑friction cart is released from rest at the top of a smooth inclined plane. The motion is recorded with a ticker timer set to 0.02 s intervals. The distances between successive dots (in centimetres) are shown in the table below. The angle of the incline is measured with a protractor. | Interval (i) | Distance between successive dots (cm) | |--------------|----------------------------------------| | 1 | 1.2 | | 2 | 1.6 | | 3 | 2.0 | | 4 | 2.5 | | 5 | 3.0 | Measured angle of the plane, θ = 15.0° (to the nearest 0.1°).

Question Parts

( a )

Calculate the instantaneous speed of the cart at the end of each interval (i = 1 to 5). Show all steps.

( b )

Using the speeds obtained in part (a), construct a v² versus s graph (where s is the cumulative distance from the start of the motion). From the straight‑line graph, determine the gradient and hence the experimental acceleration of the cart. State the relationship you used.

( c )

Theoretically, the acceleration of a body sliding down a frictionless plane is aₜ = g sinθ, where g = 9.81 m s⁻². Calculate aₜ using the measured angle, compare it with the experimental value obtained in part (b) and discuss two possible sources of error that could account for any discrepancy.
