Homework Equations
The Attempt at a Solution
I = mk^{2} = (30)(.25^{2}) = 1.875 kg m^{2}
X Direction
mv + [tex]\int[/tex] Fdt = mv_{2}
0 + O_{x}t = 0
Y Direction
mv + [tex]\int[/tex] Fdt = mv_{2}
0 + O_{y}t  30(9.81)t = 0
O_{y} = 294.3
Moments
Iw_{1} + [tex]\int[/tex]M_{O}dt = Iw_{2}
0 + 25(.3)  10(.18) = 1.875w^{2}
w = [tex]\sqrt{3.04}[/tex]
How do i relate this to velocity and time. I can use v = wr, but how can i solve for t when v = 2 m/s
2 = .3w, therefore i need to find t when w = 2/.3
