Question

If we are proving any equation of motion then why u≠0!!!!!!!

Answer 1

Answer:

The answer is :

Explanation:

See in every case the initial velocity is not always zero as if question says that like a stone is thrown from ground upwards then there the initial velocity will be zero but as soon as the question

says that calculate the final velocity when the stone was in motion for a second or two then in that there will be some value of initial velocity too.
