Calculate the kinetic energy of a 4.00kg object traveling at 16.0 m/s

Kinetic energy is 512 Joules

Explanation:

Given that,

Mass of the object, m = 4 kg

Velocity with which the object is moving, v = 16 m/s

We need to find the kinetic energy of the object. It is given by :

So, the kinetic energy of the object is 512 Joules. Hence, this is the required solution.

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
