Question

A particlemoving in a straight lives covers half the total distance with a speed it of 3 sec.and half of remaining have each cover er with speed of2 sec and the rest with a speed of3second and the averag
e speed of particle during this motion.

Answer 1

Answer:

The average speed is 2.7m/s approximately.

Explanation:

First speed = 3m/s

Second speed = 2m/s, and

Third speed = 3m/s

Average speed = Total distance / Time taken

= 3m + 2m + 3m/ 1s + 1s + 1s

= 8m / 3s

Therefore, Average speed = 2.7m/s(nearly).
