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

explanation:

areas w steep slopes, west coast, rocky mountains, and appalachian mountains

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.
