Chapter 1.1, Problem 62E

Diver's Ascent The diver in the previous exercise is supposed to stop for $5$

minutes and decompress at $150$ feet depth. Assuming that the diver will continue her ascent, after decompressing, at the same rate of $2$

feet per second, find $y\left(t\right)$

in this case and determine how long it will take the diver to reach the surface of the ocean.

Diver's Ascent After inspecting a sunken ship at a depth of $212$ feet, a diver starts her slow ascent to the surface of the ocean, rising at the rate of $2$ feet per second. Find $y\left(t\right)$, the depth of the diver, measured in feet from the ocean's surface, as a function of time $t$

(in seconds).
