A cannonball is fired with an initial velocity of 100 m/s at an angle of 35 degrees above the positive x-axis. The target is the enemy King's tower.   The cannon is positioned 300 m from the base of the King's tower, on a flat, horizontal field. The cannonball takes 3.66 s to strike the tower after it is fired. 1. At what height on the tower does the cannonball strike? 2. What is the approximate magnitude of the cannonball's velocity...
