Approach:
To find the average speed of the particle, we need to first calculate the total time taken for the particle to move from point A to point B. Then, we can find the total distance traveled by the particle and use the formula for average speed.
Calculations:
- Let the total distance between points A and B be d units.
- The particle first covers 1/4th of the distance, i.e., d/4 units, at a speed of v0.
- The time taken to cover this distance is d/4v0.
- Next, the particle covers half of the remaining distance, i.e., d/2 units, at a speed of 2v0.
- The time taken to cover this distance is d/4v0.
- Finally, the particle covers the last 1/4th distance, i.e., d/4 units, at a speed of 3v0.
- The time taken to cover this distance is d/12v0.
Total Time:
Total time taken = d/4v0 + d/2(2v0) + d/12(3v0)
Total time taken = d/4v0 + d/v0 + d/4v0
Total time taken = 3d/4v0
Total Distance:
Total distance = d/4 + d/2 + d/4
Total distance = d
Average Speed:
Average speed = Total distance / Total time taken
Average speed = d / (3d/4v0)
Average speed = 4v0/3
Therefore, the average speed of the particle moving from point A to point B is 4v0/3.
