A 1200 kg cannon fires a 100.0 kg cannonball at 35 m/s.What is the recoil velocity of the cannon? Assume that frictional forces are negligible and the cannon is fired horizontally.

Question

Quizplus · Accepted Answer

Using the conservation of momentum, the recoil velocity of the cannon can be calculated as follows: (mass of cannonball * velocity of cannonball) = (mass of cannon * recoil velocity of cannon). Solving for the recoil velocity gives: (100 kg * 35 m/s) = (1200 kg * recoil velocity), resulting in a recoil velocity of 2.9 m/s.
