# Moment of Inertia

**m/s** is the other end of the pen going when it hits the table, assuming the tip doesn't slip? Take the pen to be a uniform one dimensional rod of length 15 cm.

Two blocks of masses \(m_1=430\text{ g}\) and \(m_2=500\text{ g}\) are hanging on a pulley, as shown in the above figure. The pulley is fixed on a horizontal axle with negligible friction, and its radius is \(R=5.00\text{ cm}.\) If they are released from rest, block \(m_2\) falls \(48.0\text{ cm}\) in \(4.00\text{ s}.\) If there is no slippage between the cord and the pulley, what is the rotational inertia of the pulley?

The gravitational acceleration is \(g=9.8\text{ m/s}^2.\)
