A particle moves on a straight line and its a - t graph is shown.
List - I gives some quantites and List - II gives some possible magnitudes of quantites then correct match is
List - IList - III) Average velocity of 4 secP) 0II) Average acceleration of 4 secQ) 5III) Displacement in 4 secR) 10IV) Velocity at t = 4 secS) 20T) 40U) 50
