(v)
1. The power supply is switched on. The trolley is pulled along the track by 1 rubber band stetched to a certain length.
2. The power supply is switched off. From the ticker tape, the acceleration of the trolley is calculated using the formula a = v - ut
3. Steps 1 and 2 are repeated by pulling the trolley using N = 2, 3, 4 and 5 rubber bands stretched to the same length.
