Explanation:
Answer:
a) (u+v)/2
b) When total distance is equal to the total displacement
Explanation:
a) Let u be the initial velocity
ans v be the final velocity
Then, Average velocity = (u+v)/2 when velocity changes at uniform rate.
b) Average Speed = Total Distance/ Total Time
Average Velocity = Total Displacement/ Total Time
Given that, Avg Speed = Avg Velocity
Total Distance/ Total Time = Total Displacement/ Total Time
Total Distance = Total Displacement
Therefore, the condition is that total distance should be equal to the total displacement.
