1. A seal dives into water from a shore 6 feet high. Its path is modeled by the equation y= (1/4)x^2 -20x+6 where x is the seal's distance from land and y is the seal's depth. How many feet does the seal travel horizontally before it swims out of the water? Write your answer in radical form.

Snell's Law at its heart is a minimization problem. Light takes the path which takes the least time. The classic comparison is a lifeguard at a beach who needs to pick the correct path to get to a struggling swimmer in the least time. Assume the lifeguard can run at 2 meters/second on land, but can only swim at 1 meter/second. Have the lifeguard start at (0,5). The shoreline runs along the x-axis. The swimmer who needs help will have...

Suppose water is leaking from a tank through a circular hole of area Ah at its bottom. When water leaks through a hole, friction and contraction of the stream near the hole reduce the volume of water leaving the tank per second to cAh 2gh , where c (0 < c < 1) is an empirical constant. A tank in the form of a right-circular cone standing on end, vertex down, is leaking water through a circular hole in its...

Part I. Indicate whether true or false (T or F). ____ Storm water detention ponds typically are designed to regulate the outflow peak rate at or below a single target value, such as the pre-development (pre-land use change) peak runoff rate for a specified return period event. Detention storage alters the peak but not the volume of the outflow hydrograph. _____ Typical rating curves for weirs are concave upward. Typical rating curves for orifices are concave downward. ____ A sediment...
