Calculation
1. Stripes (n) of 10 ticks obtained : 10
2. Total time taken of the movement of the trolley (T) : T = (n) 0.2 T = 10 0.2 T = 2 second
3. Total displacement of the trolley (S)S = Total length of the 10-ticks stripesS = 0.067+0.143+0.165+0.208+0.218+0.244+0.278+0.301+0.318+0.377S = 2.319 meter
4. Average Velocity = , = = 1.16
5. Trolley acceleration
Velocity (initial), u = = = 0.335
Velocity (final), v = v = v = 1.885
Time for acceleration, t = ( n 1 ) time taken for 10 ticks t = (10 1) 0.2s t = 9 0.2 t = 1.8s
Acceleration, a = a = a = 0.861
Average velocity of trolley V =
V = V = 1.1
