(1 point) A steel ball weighing 128 pounds is suspended from a spring. This stretches the spring 528 feet. The ball is started in motion from the equilibrium position with a downward velocity of 7 feet per 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...
