A cannon is on a beach and fires a cannonball at an enemy ship sitting in the harbor. The mouth of the cannon is on an equal vertical level with the water. It can fire projectiles with an initial velocity of 80 m/s. a) When angled at 45 degrees, what is the horizontal range of the cannon (i.e., what is the horizontal displacement of a cannonball fired from this cannon)? (653.06 m) b) What is the horizontal range if the angle is raised to 60 degrees? (565.57 m) c) What if it is lowered to 30 degrees? (565.57 m)
