A horizontal pipe $10.0 \mathrm{cm}$ in diameter has a smooth reduction to a pipe $5.00 \mathrm{cm}$ in diameter. If the pressure of the water in the larger pipe is $8.00 \times 10^{4}$ Pa and the pressure in the smaller pipe is $6.00 \times 10^{4} \mathrm{Pa}$, at what rate does water flow through the pipes?

A 7.00 -g bullet, when fired from a gun into a 1.00 -kg block of wood held in a vise, penetrates the block to a depth of $8.00 \mathrm{cm} .$ This block of wood is next placed on a frictionless horizontal surface, and a second 7.00 -g bullet is fired from the gun into the block. To what depth will the bullet penetrate the block in this case?

During a certain period of time, the angular position of a swinging door is described by $\theta=5.00+10.0 t+2.00 t^{2},$ where $\theta$ is in radians and $t$ is in seconds. Determine the angular position, angular speed, and angular acceleration of the door $(a)$ at $t=0$ and $(b)$ at $t=3.00 \mathrm{s}$ .

An object of mass $m_{1}$ hangs from a string that passes over a very light fixed pulley $P_{1}$ as shown in Figure $P 5.34$ The string connects to a second very light pulley $P_{2}$. A second string passes around this pulley with one end attached to a wall and the other to an object of mass $m_{2}$ on a frictionless, horizontal table. (a) If $a_{1}$ and $a_{2}$ are the accelerations of $m_{1}$ and $m_{2},$ respectively, what is the relation between these accelerations? Find expressions for (b) the tensions in the strings and (c) the accelerations $a_{1}$ and $a_{2}$ in terms of the masses $m_{1}$ and $m_{2},$ and $g$
