In order to find the radius of the coin, we need to use:
Ac = V^2 r
In which,
Ac = acceleration of the coin = 2.2 m/s^2
V= rotational Speed = (18/12) * 2πr
r= Radius
so,
<span>2.2 = 9(π^2)(r^2) / r
</span><span>= 9(π^2)r
</span>
<span>r = 2.2 / 9(π^2) = 0.02476740044 m . . .or you can rounded it up to 0.025 m</span>
I believe it’s power, but i could be wrong!
Answer:
Hey
Your answer would be:
stationary objects within the field will move when realesed.
The reason why is because fields store potential energy as you know. when something is stationary it has potential, but when it is released that potential energy turns into kinetic energy.
this made me think of a funny joke:
A man was about to jump off of the Empire State Building when a physicist from below yield, Wait don't! you have so much potential!
lol always cracks me up.
