Question

Derive second equation of motion. A body acquires the velocity of 10 m/s in 5 sec. at a rate of

2 m / s²

. Find its initial velocity​

Answer 1

Explanation:

Given : Velocity(v) : 10m/s

Time (t) : 5 s

Accleration (a) : 2m/s²

To Find : Initial velocity (u)

Formula : v = u+at

Solution: v = u+at

So , 10 = u + 2(5)

10 = u + 10

So u = 0 m/s

Initial velocity of the body is 0 m/s
