A cannon rigidly attached to a carriage, whic can move along horizontal rails but is connected to a post by a large initially unstreched spring with a force constant k=2x10^4N/m. The cannon fires a 200kg projectile at a velocity of 125m/s directed 45 degrees above the horizontal.(adsbygoogle = window.adsbygoogle || []).push({});

a) If the mass of the cannon and its carriage is 5000kg, find the recoil speed of the cannon.

b) Determine the maximum extension of the spring.

c) Find the maximum force the spring exerts on the carriage.

d) Consider the system consisting of the cannon, carriage, and shedd. Is the momentum of this system conserved during the firing? Why or why not?

I already know the answer to d, which is no, since the spring is an external force acting on the system.

However, can someone please, help me to get started on a, b, and c?

Thank you
