I know something that a lot of people know but they get in trouble when they try to use it. I got it a long time ago from my old school buddy Ike Newton. I'll tell it to you, but you have to keep it to yourself, don't spread it around, and don't tell a lot of people where you got it.
Here it is:
<em>For every action, there is a reaction that is EQUAL and opposite. </em>
That means that if Jane pushes on the rock with 100 Newtons of force,
then <u><em>The rock pushes on Jane with 100 Newtons of force.</em></u>
It doesn't matter how much Jane's mass is, it doesn't matter what the mass of the rock is, and it doesn't even matter whether Jane is moving, or the rock is moving, or both of them are moving. If there's an action, then you can bet yer britches that there's a RE-action, and the RE-action is EQUAL and OPPOSITE to the action.
Why is this so hard ?
Answer:
The magnitude of the maximum radial acceleration of the stone is 122.034 m/s^2
Explanation:
Maximum radial acceleration (a) = w^2r
w = v/r
w^2 = (v/r)^2 = v^2/r^2
a = v^2/r^2 × r = v^2/r
v is the maximum speed the stone attains = 12 m/s
r is the radius of the circular path = 1.18 m
a = 12^2/1.18 = 144/1.18 = 122.034 m/s^2
To find the center of mass of an irregular shape using
String- for hanging at the center
• A small mass - hung from the string
• A stand-holding up the string
• A pencil pinpointing the center
• A straight-edge- Identify the middle
<h3>What is the center of mass?</h3>
Generally, a point indicates the mean location of the matter in a body or system.
In conclusion, the center of mass also indicates a point at which the body is most balanced under gravity.
