Homework Statement
There is a object traveling at 0,2m/s with a mass of 75,000kg. The object impacts a fixed point at a distance of 3.5m from its center of gravity (COG) and rotates around this point. What is the reaction force at the point of rotation?
Homework Equations
I think it is something to do with momentum and rotational velocity equations. p = m x v and v = w x r, where w = rotational velocity (rads / s) and r = radius = 3.5m in this case. I know that w = 2 x pi x f (f = frequency) and force f = p / t (where t = time). But I'm not sure how to link it all together.
The Attempt at a Solution
So far the equations are all I have... applying rotational velocity to a momentum equation... how do I do that?
