Question

please answer my questions these are so much important for me

Answer 1

Hi..........
Average velocity = Total displacement / Total time taken
Or Final velocity + initial velocity / 2
1 Case = 12m + 3m = 15 m
Time = 3sec
15/3 = 5m/s

2 Case = 12m + 12m + 12m = 36m
Time = 3+4+5 = 12sec
36/12 = 4m/s

3rd Case = 12m + 6m = 18 m
Time = 5+6+7 = 18 sec
18/18 = 1m/s..........
