If x=a+bt+ct 2 where x is in metres and t is in seconds. what is the dimensional unit of c?

m/s²

Explanation:

x = a + bt + ct²

x is in meters, so each term in the sum must also be in meters, including ct².

ct² = [m]

c[s]² = [m]

c = [m/s²]

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

technology is the application of the knowledge gained by science.
