A 2.60-kg block is attached to a horizontal spring that has a spring constant of 214 N/m. At the instant when the displacement of the spring from its unstrained length is -0.115 m, what is the acceleration a of the object? In your answer, be sure to include the proper plus or minus sign.

1. The force that the spring exerts
F=-kx=ma

a=-k(-.115)/2.60 so compute
