The first equation of motion is:
Av = u + at
Bs = ut + ½at²
Cs = vt
Dv² = u² + 2as
Answer & Solution
Correct answer: A. v = u + at
For uniform acceleration: v = u + at, where u is initial velocity, v is final velocity, a is acceleration, t is time. The other two main equations are s = ut + ½at² (distance) and v² = u² + 2as (velocity-distance).
