Explanation:
It Depends On The Question If They Give The Speed like for example ... a train slows down from 80 kmh ... its initial velocity = 80kmh and when a body is at rest its acceleration = 0 there are three formulas of equations of motion
vf = vi + at ( vf = final velocity ... vi = initial velocity and a = acceleration and t = time and S = Distance )
S = vit + 1 /2 at²
2aS = vf² - vi²
