In order to understand the possible cause of a 'right side stomach pain', it may be helpful to know the organs and structures that exist in this region of the body. Diseases, infections, or irritation of any of these organs will lead to a right side abdominal pain.
At that one instant, its velocity is zero, even though its acceleration is still 9.8 m/secÂ². But velocity cannot REMAIN at zero for any length of time if the acceleration is nonzero.
Thus momentum is conserved and, as the moment of inertia of the particle decreases, its speed increases. Recall that v = Ïr. Thus the initial angular velocity of the particle is Ï o = v/r = 3 rad/s. In addition, the initial moment of inertia of the particle is I o = mR 2 = 4m.
