A body covers one-third of the distance with a velocity `v_(1)` the second one-third of the distance with a velocity `v_(2)`, and the last one-third of the distance with a velocity `v_(3)`. The average velocity is:-

A body covers first one-third of the distance with a velocity "20ms^(-1)",the second one third with a velocity of "30ms^(-1)" and last one-third with a velocity of "40ms^(-1)".The average velocity is nearly

A body covers first one-third of the distance with a velocity 10 ms^(-1) in same direction, the second one-third with a velocity 20 ms^(-l) and last one-third with a velocity of 30 ms^(-1) . The average velocity of body is

A body covers first one-third of the distance with a velocity 10 ms^(-1) in same direction, the second one-third with a velocity 20 ms^(-l) and last one-third with a velocity of 30 ms^(-1) . The average velocity of body is

A man runs along the straight road for half the distance with velocity v_(1) and the remaining half distance with velocity v_(2) . Then the average velocity is given by

A body travelling along a straight line traversed one-third of the total distance with a velocity v_1 . The remaining part of the distance was covered with a velocity v_2 for half the time and with velocity v_3 for the other half of time. The mean velocity averaged over the whole time of motion

A particle traversed on third of the distance with a velocity v_(0) , the remaining part of the distance was covered with velocity v_(1) for half the time and with a velocity v_(2) for the remaining half of time. Assuming motion to be rectilinear, find the the mean velocity of the particle averaged over the whole time of motion.
