A group of four students is participating in a marble race. Each marble has a different mass and the same force is applied to each marble. Which marble will experience the least acceleration?

u=13

v=30

s/t=u+1\2at

=13+431/2

=13+265.5

=278.5

the rearrangement of particles in a physical change. hope this

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
