4-) The spring shown in figure below has a constant k = 20000N/m. The system fires a 200- kg projectile at V=125m/s with a 45° angle. 45.0° www a-) if the weight of the system is 5000kg, find the recoil speed b-) determine the maximum extension of the spring c-) determine the maximum force the spring exerts on the system d-) is the momentum of the whole system conserved? 4-) The spring shown in figure below has a constant k = 20000N/m.
