A cannon is rolling to the right at a speed of 0.50 c. In its own frame, it fires a 8.5 kg cannonball to the right at a speed of 0.72 c . Let A be the value of the cannonball’s momentum in the frame of the ground according to classical physics; let B be the same momentum according to special relativity. Which of the following is correct?

A cannon on a train car fires a projectile to the right with speed v0, relative to the train, from a barrel elevated at angle θ. The cannon fires just as the train, which had been cruising to the right along a level track with speed vtrain, begins to accelerate with acceleration a, which can be either positive (speeding up) or negative (slowing down). Find an expression for the angle at which the projectile should be fired so that it...
