A Bomber is practicing a bombing run. The plane is flying with a horizontal velocity of 185 m/s, and releases a bomb when it is 593 m away (horizontally) from its target and scores a direct hit. How high is the airplane flying (d_{y}) when it drops the bomb?

A sniper fires a bullet parallel to the ground. If the barrel is 0.25 meters off the ground and the initial velocity is 250 m/s, how far does the bullet travel horizontally before it hits the ground?

A rock is kicked from the ground with a velocity of 15 m/s at an angle of 15^{o} above the horizontal. What is the range (d_{x}) of the rock?
