Question

A particle moves for 20 seconds with velocity
3 ms and then velocity 4 ms for another 20
seconds and finally moves with velocity 5 ms
for next 20 seconds. What is the average
velocity of the particle?
3 ms]
4 ms
5ms
zero​

Answer 1

Answer:

5.46 m/s.

Explanation:

To calculate average speed or velocity, we need to use the formula-

Average speed =

(Total Distance travelled)/(Total time taken)

so its - (3m + 4m + 5m)/(20s + 20s + 20s)

= 11m/60s = 5.4555 = 5.46
