Question

a body travels 30m in the time 2 sec and 40 m in next 3 sec in a straight line find the average velocity and speed

Answer 1

Answer:

Average velocity and speed will be equal as body is travelling in a straight line.

Average speed = Total distance/Total time

= 30+40/2+3=70/5=14m/s

Average velocity also equals to 14m/s

Answer 2

Explanation:

A body travels in first 2 secs = 30m

A body travels in next 3 secs = 40 m

Average speed of the body = (total distance travelled/total time taken)

= 30+40/2+3

= 70/5

= 14m/sec

Hence, Average speed = Average velocity

So,the average velocity of the body is 14m/sec
