A satellite of mass 100 kg is attached centrally to a rocket stage of mass 900 kg using a separation system. In space, the satellite is separated using 10 identical spring thrusters, each having a stroke of 30 mm. Assuming the springs fully transfer their energy and the relative axial velocity achieved by the satellite after separation is 1 m/s, find the required stiffness of each spring.
