Q1-For a mass 206g oscillating on a spring, its maximum speed is 0.75m/s. If the spring constant is 71.2N/m, what is the maximum stretch (in unit of cm) of the spring during oscillation?

Q2-A spring is stretched, and stores an elastic potential energy of 332 joule. How much (in cm) has the spring be stretched if it has a spring constant of 136 N/m?

Q3For the application part of this experiment, you have a spring of spring constant 154N/m. You measured that the hanging mass has an oscillation amplitude 4.71cm, and a maximum speed 0.78m/s. How many gram is the mass?
