Q. The scale of a spring balance reading from 0 to 230 N has a length of 15.0cm. A fish hanging from the bottom of the spring oscillates vertically at a frequency of 2.40 Hz. What is the mass of the fish ignoring the mass of the spring?
Q. An 8-kg object oscillates at the end of a vertical spring that has a spring constant of 2.05 104 N/m. The effect of air resistance is represented by the damping coefficient b = 3N•s/m.
compute the frequency of the dampened oscillation.
