Question 2 A Rod Block Bullet As shown in the figure, bullet of mass 20 g is fired into a 0.5 kg block attached to the end of a 0.4 m nonuniform rod of mass 0.8 kg. The block-rod-bullet system then rotates in the plane of the figure, about a fixed axis at A. The rotational inertia of the rod alone about that axis at A is 0.64 kgm². Treat the block as a particle. (a) Find the the rotational inertia of the block-rod-bullet system about point A. 2.5 (b) If the angular speed of the system about A just after impact is 5 rads-1, what was the bullet's speed just before impact? 3.5 (c) How high will the center of mass of the rod-block-bullet system reach before coming back down again? (Assume that 0.2 J energy is lost during the collision and think about conservation of energy for solving the problem) 3

A disk initially at rest is fixed to a vertical axis of rotation and a 40 kg child is standing on the disk initially at rest 0.5 meters away from the axis of rotation. The rotational inertia of the disk is 50 kgm2. The boy pushes and jumps off the disk and the disk begins to rotate at 0.5 rad/s. Calculate the velocity of the child as they push off the disk. (The rotational inertia of the boy is mr2)
A 200-kg, 2.0-m-radius, merry-go-round in the shape of a flat, uniform, circular disk parallel to level ground is rotating at 1.2 cycles/second about an axis through its center of mass and perpendicular to the ground. A 50-kg boy jumps onto the edge of the merry-go round and lands at a fixed point. What is the angular velocity of the merry-go-round after the boy lands on it? Hint: = (1/2)mR2 where m is the mass of the disk and R is the radius of the disk.
