if a runner takes 9 seconds to achieve a velocity of 11.1 m/s what is his acceleration and what distance did he cover?

d they tend to lose electrons and become cations.

explanation:

truck y has a greater velocity than truck x.

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

i would say
