$7)$ Two masses, A and B$,$ are attached to different springs. Mass A vibrates with an amplitude of $8$ cm at a

frequency of $10$ Hz and mass B vibrates with an amplitude of $5$ cm at a frequency of $16$ Hz$.$ How does the

maximum speed of A compare to the maximum speed of B$?7)\_\_\_\_\_\_\_$

A$)$ Mass A has the greater maximum speed.

B$)$ They are equal.

C$)$ Mass B has the greater maximum speed
