To practice problem-solving strategy 8.1 conservation of momentum. protecting his nest, a 600-g peregrine falcon rams a marauding 1.5-kg raven in midair. the falcon is moving at 20.0 m/s , and the raven at 9.00 m/s at the moment of impact. the falcon strikes the raven at right angles to the raven's direction of flight and rebounds straight back with a speed of 5.00 m/s . by what angle does the impact change the raven's direction of motion?

The angle as calculated is

Solution:

As per the question:

Mass of falcon,

Mass of raven,

Initial speed of the falcon,

Initial speed of the raven,

Rebounding speed of the falcon,

Now,

To calculate the angle at which the direction of motion of the raven changes:

By using the principle of conservation of momentum:

The angle of the change of the raven's direction is given by:

gravititional force is a force that is acting around you, it is non-contactable and it is a force that pulls you to the core of the earth.

brainliest

the independent variable, or the one that is intentionally manipulated is the speed.
