A 48-Kg Block Attached to an Ideal Spring Executes Simple Harmonic

Multiple Choice

A 4.8-kg block attached to an ideal spring executes simple harmonic motion on a frictionless horizontal surface.At time t = 0.00 s,the block has a displacement of $$- 0.90 \mathrm {~m}$$ a velocity of $- 0.80 \mathrm {~m} / \mathrm { s } \text {, }$ and an acceleration of $+ 2.9 \mathrm {~m} / \mathrm { s } ^ { 2 }$ The spring constant of the spring is closest to

A) 15 N/m.
B) 14 N/m.
C) 13 N/m.
D) 12 N/m.
E) 11 N/m.
