Someone please help asap Question 4: If a body of mass 4 kg moves at a velocity of 25 mls and has a 2 points
completely inelastic collision with a body of mass 10 kg, the final velocities
of both the bodies is 14 m/s. Calculate the initial velocity of the body of
mass 10 kg."

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
