# 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.

$F_1=110\text{ N}$ and $F_2=70\text{ N}$ are acting on it, as shown above. If the mass of the cylinder is $100\text{ kg},$ what is the rotational acceleration produced by the two forces?

A cylinder is pinned at its center and two forces$m_1=430\text{ g}$ 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?

Two blocks of massesThe gravitational acceleration is $g=9.8\text{ m/s}^2.$
