A 5.00 kg wood cube rests on a frictionless horizontal table. It has two springs attached to it on opposite faces. The spring on the left has a spring constant of 55.0 N/m, and the spring on the right has a spring constant of 111 N/m. Both springs are initially in their equilibrium positions (neither compressed nor stretched). The block is moved toward the left 10.0 cm, compressing the left spring and stretching the right spring. (a) Calculate the resulting net force on the block. (b) Calculate the the initial acceleration of the block when it is released. Use the convention that to the right is positive and to the left is negative.
