second. The air resistance (in pounds) of the moving ball numerically equals 4 times its velocity (in feet per second)
Suppose that after t seconds the ball is y feet below its rest position. Find y in terms of t. (Note that the positive direction is down.)
Take as the gravitational acceleration 32 feet per second per second.
y =
