Calculate the net work done by the wings of a 0.300 kg hawk as he flies in a straight line at an angle of 35° above the horizontal from a height of 10.0 m to a height of 50.0 m. his starting speed is 6.00 m/s and his final speed is 10.0 m/s. the drag force is an average of 2.5 n during the flight

Explanation:

As we know by work energy theorem that net work done by all forces is equal to change in kinetic energy

so here we can say

now we know that when plane moves upwards then

Now work done by drag force is given as

now we have
