James Bond trying to jump from a helicopter into a speeding Corvette to catch in the backyard. The car is going 30.0 m/s in the helicopters flying complete game horizontal at 100 m/s the helicopter is 120 m above the car in 440 m behind a car. How long must James Bond wait to jump in order to safely make it into the car?

positive reinforcement? ?

i think its c if i'm wrong

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
