small songbird with a mass of 0.015 kg is standing on a branch. A falcon with a mass of 0.810 kg catches the song bird in the air while flying horizontally with a velocity of 8.30 m/s. How much kinetic energy is lost in the collision when the falcon catches the songbird ( both fly off horizontally in the same direction as the falcon? Express your answer to two decimal places in units of Joules, but do not include units in your answer.
