Calculate the momentum of a 1200kg car with a velocity of 25m/s

Momentum, p = 30000 kg-m/s

Explanation:

It is given that,

Mass of the car, m = 1200 kg

Speed of the car, v = 25 m/s

To find,

The momentum of car.

Solution,

We know that the product of mass and velocity is called momentum of an object. It is given by :

p = 30000 kg-m/s

So, the momentum of the car is 30000 kg-m/s. Hence, this is the required solution.

the gas collects in coils that then becomes a liquid that then flows through the coils inside the refrigerator

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
