At a particular instant the magnitude of the momentum of a planet is 2.25 times 1029 kg m/s, and the force exerted on It by the star It is orbiting is 9.2 times 1022 N. The angle between the planet's momentum and the gravitational force exerted by the star is 129degree. What is the parallel component of the force on the planet by the star? What will the magnitude of the planet's momentum be after 8 h? (Enter your answer to at least four significant figures.)

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
