1. A sparrow and a crow are having the same kinetic energy during a flight, Which of the two is moving fast and why?


As we know , K.E. = 1/2 mv2 . Having the same kinetic energy for sparrow and crow, velocity of the sparrow will be greater because mass of sparrow is smaller than crow.
Thus, the sparrow is moving fast.
