1. A spring stretches 5.0 cm when a 200.-gram mass is hung from it and set to equilibrium.
What is its spring constant?
2. When that spring in its unstretched state, if that mass is hung on the spring and
immediately let go, what will be the period (duration) of its oscillations?
3. A pendulum clock has a two-foot-long pendulum. The gears of the clock should be
calibrated so that how many cycles of the pendulum cause the clock hands to advance one
minute?
