The first stage type of rocket used in Moon missions provides an unbalanced upward force of 30MN and burns for 2.5 minutes. a) Calculate the increase in momentum that results from the equation F=(mv-mu)/t

b) If the rocket has a mass of 3000 tonnes what is the velocity of the rocket after the first stage has completed its 'burn'?

Explanation:hh

uranium fissions/breaks up giving out energy and neutrons

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
