Asoccer ball has 1200 j of kinetic energy and a mass of o.8 kg what is the speed of the ball when it is kicked

F=MA
1200 j = (0.8 kg)(A)
1200 j / 0.8 kg = A
A= 1500 m/s^2 

Sounds propagates through some kind of medium. usually it's air, but it goes just as well through solid objects like walls, windows etc. a soundwave will compress the (air)molecules in front of it, and if this increased density wave hits your ears, you register it as sound. solid objects like walls are a lot denser than air, this means that they will damp a wave, but also carry it easier.

Motion i think. hope it
