You fall off a building that is 11.8 meters tall. How fast in meters per second will you hit the trampoline that is conveniently placed at ground level?

need to see circuit to get time constant

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

im srry but ur wrong the answer is d a smooth rock, some red dirt, and an empty bird's nest.
