The velocity-time plot for a particle moving on a straight line is shown in the figure, then

Find the average velocity of a particle moving along a straight line such that its velocity changes with time as v (m//s) = 4 sin. (pi)/(2) t , over the time interval t = 0 to t = (2n - 1) 2 seconds. (n being any + ve integer).

  • Assertion: When a particle moves with constant velocity its average velocity, its insttantaneous velocity and its speed are all equal in magnitude. Reason: If the average velocity of a particle moving on a straight line is zero in a time interval, then it is possible that the instantaneous velocity is never zero in the internal.

    A
    If both assertion `&` Reason are True `&` the Reason is a corrrect explanation of the Asserion.
    B
    If both Assertion `&` Reason are True but Reason is not correct explanation of the Assertion.
    C
    If Assertion is Trie but the Reason is False.
    D
