Answer» n : A body covers the first one third distance with a velocity 'a', the second one third of the distance with a velocity 'B' WND the remaining with a velocity 'c'. The AVERAGE velocity is : Solution : Let the total distance covered by the body is d. We know that, Velocity = Displacement/Time For the first one third of distance, For the second one third of distance,For rest of the distance,We know that, From equations (1),(2) and (3) : Average velocity of the body is 3abc/ab + bc + ca |
