Question 3 NECO • 2025 • PHYSICS • practical

A student investigates the motion of a cart down a smooth inclined plane using a ticker timer. The ticker timer marks a dot on a ticker tape at every 0.02 s. The distances (in cm) between successive dots recorded are: 2.1, 2.5, 3.0, 3.6, 4.3, 5.1, 6.0, 7.0, 8.1, 9.3. Using this data, answer the following:

( a )

Calculate the average speed of the cart over the whole run.

( b )

Estimate the instantaneous speed of the cart at the instant of the 5th dot by averaging the speeds of the 4th‑5th and 5th‑6th intervals.

( c )

Assuming the motion is uniformly accelerated, determine the acceleration of the cart using the method of successive differences of speed.

( d )

State two possible sources of error that could affect the accuracy of the calculated acceleration.
