Question

Acceleration of body is given by________, where u = initial speed, v = final speed, t = time taken.

  1. (u - v)/t
  2. (v - u)/t
  3. t/ (v - u)
  4. t/ (u - v)

hintHint:

a=(v-u)/t

The correct answer is: (v - u)/t


    • Acceleration is given by change in velocity upon change in time.
    • Change is velocity= final speed - initial speed = v - u
    • Therefore, acceleration = (v- u)/t.
    • So, the correct option is b.
