Question

A body travels towards north with 2m/s for 20 sec and then moves towards east with
velocity 3m/s for 10sec. Its average velocity is

Answer 1

Answer:

1.4 m/s towards northeast.

Explanation:

In order to find average velocity, we have to divide the total distance covered by total time taken.

So, average velocity = total distance / total time.

Here the distances covered is 20×2m=40m+10×3m=30

40m + 30m = 70m

the time taken is 20sec+30sec= 50 sec

Average velocity is 70/50= 1.4 m/s.

Direction is East and North. So, the average direction is north-east.

Therefore, Average displacement is 1.4 m/s towards northeast.
