Scientists estimate that a certain meteorite had a mass of about 1.4 10^8 kg (around 150,000 tons) and was traveling at nearly 12 km/s when it struck the earth. About how long would it take a standard coal fired power plant which generates about 1 billion joules per second to generate the same amount of kinetic energy as the meteorite when it hit the ground?

explanation:

a = acceleration

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
