An 82 kg man on a diving board drops from rest 3.0 m above the surface of the water and he comes to rest 0.55 s after reaching the water. What is the average net force on the diver as he is brought to rest? Remember to first find the velocity of the man after he falls 3.0 m off of the diving board.

the first, second, and fifth options

i think the answer would be reserve.

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
