A student measures the maximum speed of a block

undergoing simple harmonic oscillations of amplitude

A on the end of an ideal spring. If the block is

replaced by one with twice the mass but the amplitude

of its oscillations remains the same, then the

maximum speed of the block will

(A) decrease by a factor of 4

(B) decrease by a factor of 2

(C) decrease by a factor of

(D) remain the same

(E) increase by a factor of 2
