    Two projectiles are launched into the air. The first projectile has a y-component of its initial velocity of 10 m/s and an x-component of its initial velocity of 10 m/s. (This is equivalent to an initial speed of 14.2 m/s at a 45 degree angle.) The second projectile also has a y-component of its initial velocity of 10 m/s but an x-component of 5 m/s for its initial velocity. (This is equivalent to an initial speed of 11.2 m/s at...
