What is the resultant force acting on a ball thrown up with a force of 10 n when the wind is blowing westward with a force of 5 n?

11.2 N, 63.4 degrees up of west

Explanation:

The two forces (upward, 10 N, and westward, 5 N) are acting perpendicular to each other. This means that we can find the magnitude of the resultant force by using Pythagorean's theorem:

The direction of the resultant force instead is given by

with the angle measured with respect the west direction.

im sorry i dont know

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
