2. Consider point objects each with mass 1.0 [kg] positioned at the corners of an equilateral triangle with side 1.0 [m]. a. What is the total moment of inertia of the point objects about an axis perpendicular to the triangle and passing through the center? (2.5points) b. Use parallel-axis theorem to calculate the total moment of inertia about an axis perpendicular to the triangle and passing through one of the corners. (2.5points)
