So, this question was asked in my recent test and it seems to be puzzling everyone..... At t = 0,a particle starts from rest at the origin. The acceleration of particle varies with time as a= 2t m/s 2 where t is in second.Let time average velocity of the particle be v 1 and distance average velocity is v 2 for time duration t=0 to t=3s .choose the correct option(s). (A) v 1 = 3 m/s (B) v 2 = 9/5 m/s (C) v 1 = 5 m/s (D) v 2 = 27/5 m/s
