A Mass Hanging from the End of a Spring Has $\omega=6.3 \mathrm{~s}^{-1} \approx 1$

Multiple Choice

A mass hanging from the end of a spring has a phase rate of $\omega=6.3 \mathrm{~s}^{-1} \approx 1$ cycle/s. Let's define $t=0$ to be when the mass passes $x=0$ going up. If its speed as it passes is $1.0 \mathrm{~m} / \mathrm{s}$ , what is its amplitude $A$ ?

A) 0
B) $\mathbf{0 . 1 6} \mathrm{m}$
C) $1.0 \mathrm{~m}$
D) $6.3 \mathrm{~m}$
E) We are not given enough information to answer.
F) Some other result (specify)
