Question

Average velocity of a particle moving in a straight line, with constant acceleration ‘a’ and initial velocity 'u' in first 't' seconds is :


  1. (u + at)/2

  2. u + at

  3. u

  4. u + (at/2)


Solution

The correct option is D

u + (at/2)


AverageVelocity=Total displacementTotal time

AverageVelocity=ut+at22t

                                   =u+at2
