To protect their young in the nest, peregrine falcons will fly into birds of prey (such as ravens) at high speed. in one such episode, a 600-g falcon flying at 20.0 m/s hit a 1.50-kg raven flying at 9.0 m/s. the falcon hit the raven at right angles to its original path and bounced back at 5.0 m/s. (these figures were estimated by the author as he watched this attack occur in northern new mexico.) (a) by what angle did the falcon change the raven’s direction of motion? (b) what was the raven’s speed right after the collision?

Part a)

Part b)

Explanation:

Part a)

mass of the Falcon bird is given as

initial speed of the bird is

final speed of the bird is given as

(opposite direction)

So here the impulse given by falcon bird is given as

now the final momentum of Raven bird in perpendicular direction is given as

now the change in the angle of the raven bird is given as

Part b)

Final speed of the raven bird is given as

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..

hello there!

your answer is a “generator”

a generator does not create energy but instead it transforms it.

it’s basically a motor working in reverse.
