 A mass m=0.25 kg is attached to an ideal Hooke's Law spring
which has a spring constant k=10 N/m=10 kg/s^{2}. If the mass glides
back and forth on a frictionless horizontal surface, find the period
of oscillation.
 If the same spring is used (k=10 N/m), but the mass is doubled
(m=0.50 kg), what is the new period of oscillation?
 If the original mass is used (m=0.25 kg), but the spring is
made twice as stiff (k=20 N/m), what is the new period of oscillation?

 A mass m=0.25 kg is suspended from an ideal Hooke's Law spring
which has a spring constant k=10 N/m=10 kg/s^{2}. If the mass moves
up and down in the Earth's gravitational field near the Earth's surface,
find the period of oscillation.
 If the same spring is used (k=10 N/m), but the mass is doubled
(m=0.50 kg), what is the new period of oscillation?
 If the original mass is used (m=0.25 kg), but the spring is
made twice as stiff (k=20 N/m), what is the new period of oscillation?
 Suggest a way to measure the spring constant k of a spring that is
fundamentally different from the method in this week's lab.
What quantities must be measured?
 If y and x are related through the equation
y = (3 x + 7)^{½}, then a
graph of y vs. x looks like this curve
What function of y should be plotted vs. x to produce a
straight line?
