In the figure, a 6.09 g bullet is fired into a 0.650 kg block attached to the end of a 0.129 m nonuniform rod of mass 0.266 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 A is 0.0740 kg·m². Treat the block as a particle. (a) What then is the rotational inertia of the block-rod-bullet system about point A? (b) If the angular speed of the system about A just after impact is 6.91 rad/s, what is the bullet's speed just before impact?Diagram Explanation: The diagram shows a vertical rod labeled "Rod," fixed at a pivot point labeled "A" at its top end. Attached at the bottom of the rod is a block labeled "Block." An arrow pointing horizontally towards the block represents a "Bullet."Question (a) has an input box for "Number" and a dropdown for "Units."Question (b) also has an input box for "Number" and a dropdown for "Units."

A pool ball is struck directly in its center so that it begins to slide across the table without rotating. Eventually, friction with the table causes it to roll without slipping. The mass of the ball is M and its radius is R. The coefficient of friction between the ball and the table is u. If the initial speed of the ball is vo, what is its final speed, once it is rolling without slipping?
A wad of sticky clay with mass m and velocity vi is fired at a solid cylinder of mass M and radius R.

A uniform thin rod of length 0.70 m and mass 5.5 kg can rotate in a horizontal plane about a vertical axis through its center. The rod is a rest when a 3.0-g bullet traveling in the horizontal plane of the rod is fired into one end of the rod. As viewed from above, the direction of the bullet velocity makes an angle of 60° with the rod (see the figure). If the bullet lodges in the rod and the angular velocity of the rod is 11.0 rad/s immediately after the collision, what is the magnitude of the bullet's velocity just before impact?
