A block whose massis 650 gm is fastened to a spring of spring constant K equals 65 N/m whose other end is fixed. The block is pulled a distance x = 11 cm from its equilibrium position at x = 0 on a smooth surface, and released from rest at t= 0. The maximum speed‘S’ of the oscillating block is

A

11 cm/sec

B

11 m/sec

C

11 mm/sec

D

1.1 m/sec
