1. The problem statement, all variables and given/known data I am struggling with a simple point. Suppose a particle of mass 'm' is located at (a, b) in XY plane (a,b > 0). Gravity is in -Y direction. The particle is to let fall under gravity. Suppose it falls by a height 'h' after some time 't'. I have two questions. (i) What is moment of inertia of the point mass about the point (0, b) (ii) What is the moment of inertia of the point mass about the axis passing through O parallel to Z axis. 2. Relevant equations 3. The attempt at a solution My answers are: (i) m (a^2 + h^2) (ii) ma^2 Comment if possible, thx in advance.
