A block with mass m = 4.2 kg is attached to two springs with spring constants...

A block with mass m = 4.2 kg is attached to two springs with spring constants k_left = 34 N/m and k_right = 57 N/m. The block is pulled a distance x = 0.22 m to the left of its equilibrium position and released from rest

Where is the block located, relative to equilibrium, at a time 0.8 s after it is released? (if the block is left of equilibrium give the answer as a negative value; if the block is right of equilibrium give the answer as a positive value)

What is the net force on the block at this time 0.8 s? (a negative force is to the left; a positive force
