A particle starts from rest and traverses a distance l with uniform acceleration, then moves uniformly over a further distance 2l and finally comes to rest after moving a further distance 3l under uniform retardation. Assuming entire motion to be rectilinear motion, the ration of average speed over the journey to the maximum speed on its way is:
- 1
- 2
- 3
- 4
- 5
- 6
- 7
- 8
- 9
- 10
