Question

A system of point particles is shown in the following figure. Each particle has mass 0.3 kg and they all lie in the same plane. a. What is the moment of inertia of the system about the given axis (imagine the axis is out of the page)? b. If the system rotates at 5 rev/s, what is its rotational kinetic energy? 40 cm axis 20 cm 60 cm

Step 1

The moment of inertia is given by the formula I = m*r^2, where m is the mass of the particle and r is the distance from the axis of rotation. For the particle at 40 cm, I = 0.3 kg * (0.4 m)^2 = 0.048 kg*m^2. For the particle at 20 cm, I = 0.3 kg * (0.2 m)^2 = Show more…
