A student is observing the oscillations of a mass on the end of a spring. The spring has a force constant of 6 x 10^-5N/m, and the mass is 0.15 kg. She pulls it 6 cm below equilibrium and lets it go. She now writes an equation which she believes describes the motion of the mass. In her description, the y axis is vertical, and UP is positive. Her equation is
y = (3 cm) sin ( 0.02 sec^-1 t + 3.14)

    (A) Does she have the amplitude right?   If not, what was right? If yes, explain.
    (B) Does she have the frequency right?   If not, what was right? If yes, explain.
    (C) Does she have the phase angle right? If not, what was right? If yes, explain.
