A block whose mass m = 680g is fastened to a spring whose spring constant k = 65N/m. The block is pulled a distance x = 11cm from its equilibrium position at x = 0 on a frictionless surface and released from rest at t = 0. What are the amplitude x m , maximum speed v m and magnitude a m of the maximum acceleration of the oscillation in SI system?
A.
x m = 1.11m, v m = 1.1m/s , a m = 11m/s 2
B.
x m = 0.11m, v m = 2.1m/s , a m = 11m/s 2
C.
x m = 0.11m, v m = 1.1m/s , a m = 11m/s 2
D.
x m = 0.11m, v m = 1.1m/s , a m = 1m/s 2
