Question

What shape is the trajectory (graph ofy vs. x) of the shells? -straight line -parabola
-hyperbola -the shape cannot be determined For two shells fired at the same speed whichstatement about the horizontal distance traveled is correct? For two shells fired at the same speed whichstatement about the horizontal distance traveled is correct? Consider the situation in which bothshells are fired at an angle greater than 45 degrees with respectto the horizontal. Remember that enemy ship A is closer than enemyship B. Consider the situation in which bothshells are fired at an angle greater than 45 degrees with respectto the horizontal. Remember that enemy ship A is closer than enemyship B. -A -B -Both shells are fired at the same angle -A -B -Both shells are fired at the same angle -A -B -Both shells are fired at the same angle Which shell reaches the greater maximum height? -A -B -Both shells are fired at the same angle -A -B -Both shells are fired at the same angle Which shell has the longest travel time (time elapsed betweenbeing fired and hitting the enemy ship)? -A -B -Both shells are fired at the same angle -A -B -Both shells are fired at the same angle A battleship simultaneously fires two shells toward twoidentical enemy ships. One shell hits ship A, which is close by,and the other hits ship B, which is farther away. The two shellsare fired at the same speed. Assume that air resistance isnegligible and that the magnitude of the acceleration due togravity is g . What shape is the trajectory (graph ofy vs. x) of the shells? -straight line -parabola -hyperbola -the shape cannot be determined For two shells fired at the same speed whichstatement about the horizontal distance traveled is correct? -The shell fired at a larger angle withrespect to the horizontal lands farther away. -The shell fired at an angle closest to 45 degrees lands fartheraway. -The shell fired at a smaller angle with respect to the horizontallands farther away -The lighter shell lands farther away. Consider the situation in which bothshells are fired at an angle greater than 45 degrees with respectto the horizontal. Remember that enemy ship A is closer than enemyship B. -A -B -Both shells are fired at the same angle Which shell is launched with a greater vertical velocity, vy ? -A -B -Both shells are fired at the same angle Which shell reaches the greater maximum height? -A -B -Both shells are fired at the same angle Which shell has the longest travel time (time elapsed betweenbeing fired and hitting the enemy ship)? -A -B -Both shells are fired at the same angle

Explanation / Answer
