Motion in A Straight Line question

2021 · 25 Feb · Shift 1 · Q54

JEE MainPhysicsMotion in A Straight LineMCQ+4 / −1
An engine of a train, moving with uniform acceleration, passes the signal-post with velocity u and the last compartment with velocity v. The velocity with which middle point of the train passes the signal post is :
  1. A
    u+v2{{u + v} \over 2}2u+v​
  2. B
    v2−u22\sqrt {{{{v^2} - {u^2}} \over 2}}2v2−u2​​
  3. C
    v−u2{{v - u} \over 2}2v−u​
  4. D
    v2+u22\sqrt {{{{v^2} + {u^2}} \over 2}}2v2+u2​​
