A student is investigating the motion of a cart down a smooth inclined plane using a ticker timer. The plane is fixed at an angle of 5° to the horizontal. The mass of the cart (including wheels) is 0.50 kg. The ticker timer produces dots at intervals of 0.02 s. The student records the distances between successive dots as shown in the table below. | Dot interval | Distance between successive dots (cm) | |--------------|----------------------------------------| | 1–2 | 2.1 | | 2–3 | 2.3 | | 3–4 | 2.5 | | 4–5 | 2.8 | | 5–6 | 3.0 | | 6–7 | 3.3 | | 7–8 | 3.6 | | 8–9 | 4.0 | | 9–10 | 4.4 | Using the data, the student is required to:

Question Parts

( a )
Calculate the instantaneous velocity of the cart at each recorded dot and determine the average acceleration over the interval using the method of successive velocities.
( b )
From the average acceleration obtained, calculate the coefficient of kinetic friction (µ) between the cart and the plane, assuming the only forces acting are gravity, the normal reaction and kinetic friction.
( c )
Identify two possible sources of systematic error in this experiment and suggest a practical way to minimise each.
