B) 0.732 J
C) 1.05 J

What will be an ideal response?
A 1.6-kg block on a horizontal frictionless surface is attached to an ideal massless spring whose spring constant is 190 N/m
The block is pulled from its equilibrium position at x = 0.00 m to a displacement x = +0.080 m and is released from rest. The block then executes simple harmonic motion along the horizontal x-axis. What is the velocity of the block at time t = 0.40 s? A) 0.82 m/s B) -0.82 m/s C) 0.30 m/s D) -0.30 m/s E) 0.00 m/s
