A go-kart accelerates at a rate of 12.0 m/s2 How long will it
take the go-kart to reach a
speed of 25 m/s?

please hurry

if it is at a speed of 12.5 m / s it would take 2 minutes

Explanation:

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
