(a) conserve momentum: initial p = final p
0 = 1100kg * 595m/s + 5.85e7kg * v
v = -0.011188 m/s = -11.2 mm/s
(b) Ek = ½(1100kg * (595m/s)² + 5.85e7kg*(0.011188m/s)²) = 194.7

A battleship that is 5.85 times 10^7 kg and originally at rest fires a 1100-kg artillery...
A cannon of mass 5.60 ✕ 10^3 kg is rigidly bolted to the earth so it can recoil only by a negligible amount. The cannon fires an 82.5-kg shell horizontally with an initial velocity of +550 m/s. Suppose the cannon is then unbolted from the earth, and no external force hinders its recoil. What would be the velocity of an identical shell fired by this loose cannon? (Hint: In both cases assume that the burning gunpowder imparts the same kinetic...
1. A gun fires a shell of mass 8 kg in a horizontal direction with a velocity of 375 m-s. The mass of the gun is 2 t and the shell takes 0.012 s to leave the barrel. Calculate the velocity of recoil and the average force on the gun. 2. Two men, one of mass 80 kg and the other 60 kg, sit facing each other in two light boats and holding the ends of a rope between them....
A cannon of mass 5.93 x 103 kg is rigidly bolted to the earth so it can recolil only by a negligible amount. The cannon fires a 80.7kg shell horizontally with an initial velocity of 508 m/s. Suppose the cannon is then unbolted from the earth, and no external force hinders its recoil. What would be the velocity of a shell fired from this loose cannon? (Hint: In both cases assume that the burning gunpowder imparts the same kinetic energy...
2) The Oasis of the Seas has a mass of 10° kg and is floating tionless in the ocean. You are standing on its rear deck. You take a 0.15 kq baseball out of your pocket and throw it from the rear deck. away from the ship with a velocity of 30 m/s (about 60 mph) at an angle of20° above the horizontal. 10 pts) How fast does the Oasis move (horizontally) and in what direction? Do not consider any...
