I have already tried that but the answer is too small.. It should be 1. something but when i use this 20 degree angle i get 0.07 something... which is totally wrong..
\tau = (1700kg)(9.8m/s2)(5m) + (1000kg)(9.8m/s2)(7m) = 151900kgm2/s2
I = Ib + Ig = \frac{1}{3}(1700kg)(8m)2 + (1000kg)(7)2 = 85266.67kgm2
\alpha = \frac{\tau}{I} = 1.78rad/s2
But this \alpha is wrong.. where did i go wrong?
Yes I went through this link. So the
Ib = (m/3)L2
Is this right? Then what about inertia for the person and his horse? How to calculate that? The only way I know is I = (1000g)(L-1)2.
