A particle undergoes two displacements. The first has a magnitude of 11 m and makes an angle of 73 ◦ with the positive x axis. The result after the two displacements is 8.7 m directed at an angle of 119◦ to the positive x axis using counterclockwise as the positive angular direction Find the angle of the second displacement (measured counterclockwise from the positive x axis). Answer in units of ◦

7.97253265907 m

Explanation:

First displacement

Final displacement

Second displacement

The magnitude of the second displacement is

The second displacement is 7.97253265907 m

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
