You are driving down the highway when you find yourself behind a very slow car traveling at 36 m/s. You decide to change lanes and accelerate at 2.9 m/s2 for the next 3.0 s. What is your final velocity?

hypothesising or postulating

if they have a finite resultant

im guessing the west of station b

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
