Jack and jill are maneuvering a 3000 kg boat near a dock. initially the boat's position is < 2, 0, 3> m and its speed is 1.3 m/s. as the boat moves to position < 4, 0, 2> m, jack exerts a force of< -400, 0, 200> n, and jill exerts a force of < 150, 0, 300> n. what is final speed of the boat?

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
