A body weighing 2 pounds forces hangs from a spring with constant 4 lb / ft. The medium in which the body moves offers a resistance force to movement that is numerically equal to its instantaneous speed. If the weight is released 1/3 feet above its balance position with a downward speed of 9 feet per second, determine the speed at which time it passes through the balance position. Consider negative downward and positive upward magnitudes.

A body weighing 10 pounds forces hangs from a spring with constant 4/5 lb / ft. The medium where the body moves it offers a resistance force to movement that is numerically equal to its instantaneous speed. If the weight is released 5/3 feet above your balance position with a downward speed of 6 feet per second, determine the position the lower the object reaches. Consider negative downward and positive upward magnitudes
