A cannon is rigidly attached to a carriage which can move, Ask an Expert

Academics

A cannon is rigidly attached to a carriage, which can move along horizontal rails, but is connected to a post by a large spring, initially unstretched and with force constant k = 1.76 104 N/m, as in the figure below. The cannon fires a 200-kg projectile at a velocity of 150 m/s directed 45.0° above the horizontal.

(a) If the mass of the cannon and its carriage is 5,000 kg, find the recoil speed of the cannon.

m/s

(b) Determine the maximum extension of the spring.

(d) Consider the system consisting of the cannon, the carriage, and the shell. Is the momentum of this system conserved during the firing? Yes No Why or why not?
