A solid disk of mass M = 1.5 kg and radius R = 0.10 m is hanging from a massless thin rod of length D = 1.2 m.
(a) What is the rotational inertia of the disk-rod system with respect to the attachment point P?
(b) A bullet with mass m = 20.0 g is fired horizontally towards the center of mass of the disk with a speed of v0 = 500m/s. In unit vector notation, what is the angular momentum L of the bullet with respect to point P just before it collides with the disk? Use the coordinate system with axes as shown in the figure, with the z-axis out of the page.
(c) After the very short collision, the bullet gets embedded in the disk. In unit vector notation, what is the angular velocity ω of the thin rod-bullet-disk system just after the collision?
(d) Find the distance h to which the center of mass of the disk-bullet system swings after the collision.

A block of mass 2.1 kg, which has an initial velocity of 5.3m/s at time t = 0, slides on a horizontal surface. Determine the distance that the block slides as it comes to rest
A neutral copper bar oriented horizontally moves downward through a region where there is a magnetic field out of the page. Which diagram correctly shows the distribution of charge on the bar?
The masses of the earth and moon are 5.98 × 1024 and 7.35 × 1022 kg, respectively. Identical amounts of charge are placed on each body, such that the net force (gravitational plus electrical) on each is zero. What is the magnitude of the charge place..
