A block with mass m is connected to two springs having constant forces k1=2k and k2=k. The system is initially in equilibrium on a horizontal, frictionless surface. Then, the block is pushed d distance to the right from rest, a. Draw the free body-diagram for the system and calculate the work done by the acting all forces. b. After the block release what will be the maximum speed of the block and what will be the maximum compression of spring 1?
