Step 1
First, we need to find the spring constant, k, of the spring. We can use Hooke's Law, which states that the force exerted by a spring is proportional to its displacement from equilibrium. In this case, the weight of the ball is balanced by the force exerted by the Show more…

A steel ball weighing 128 pounds is suspended from a spring. This stretches the spring 128/65 feet. The ball is started in motion from the equilibrium position with a downward velocity of 8 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 is y feet below its rest position. Find y in terms of t. (Note that this means that the positive direction for y is down.) y= Take as the gravitational acceleration 32 feet per second per second.

A hollow steel ball weighing 4 pounds is suspended from a spring. This stretches the spring 1717 feet. The ball is started in motion from the equilibrium position with a downward velocity of 55 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 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=

A hollow steel ball weighing 4 pounds is suspended from a spring. This stretches the spring 14 feet. The ball is started in motion from the equilibrium position with a downward velocity of 4 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 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 =
