A projectile is any object that is thrown or launched into the air and then is only influenced by the force of gravity. For an object to become a projectile, some initial force must be imparted upon it. A baseball that has been hit by a batter, a cannonball fired from a cannon or ...
The Taiping case was hardly helped when a cannonball fired from the Nanjing battlements, the Taiping defenders mistaking Elgin’s ship for an enemy, narrowly missing Elgin himself. 太平天国的举措也被一记反助攻,在南京的战役中,一颗炮弹发射出来,差点击中被太平天国守军误认为是敌人的额尔金的船只上的其...
A cannonball is fired from a gun with a muzzle velocity of 75 m/s at an angle of 65^{\circ} above the horizontal. What are the x and y components of the initial velocity? How long (in seconds) will th A projectile is fired...
The promise of fixity also belied the material vulnerability of the statue. Like humans, sculptures suffered mutilations that could not always be concealed—or, in the case of enslaved people, that slaveholders intended to remain dreadfully evident. In 1780, a cannonball fired from an offshore ...

As early as the late 16th Century, naval gunners knew that a cannonball fired at a sufficiently small impact angle to the water surface could be made to skip across the sea1. The technique simplified targeting because skipping spheres would strike any object along a straight line, rather than...
