A car accelerates uniformly from rest to a speed of 18 m/s in 12 seconds. Find the acceleration of the car over this period.

The correct answer is

Explanation:

In general terms, the acceleration refers to how velocity changes or increases. This is measured in meters per second squared () or similar units such as kilometers per hour squared (). Moreover, to calculate acceleration it is necessary to subtract the initial velocity from the final velocity and then divide this into the time. The formula and operation are shown below:

   (Initial velocity is 0 m/s because the car was at rest)

According to this, the acceleration of the car was

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
