A battleship simultaneously fires two shells toward two identical enemy ships. One shell hits ship A, which is close by, and the other hits ship B, which is farther away. The two shells are fired at the same speed. Assume that air resistance is negligible and that the magnitude of the acceleration due to gravity is g .
1.Which shell is launched with a greater horizontal velocity, v2?
2. Which shell reaches the greater maximum height?
Which shell has the longest travel time (time elapsed between being fired and hitting the enemy ship)?
