a projectile is launched in the horizontal direction. It travels 2.050 m horizontally while it falls 0.450 m vertically, and it then strikes the floor. What was the original velocity of the projectile? How long was it in the air?

• Physics -

well, how long does it take to fall .450 m? Get t sec.

velocity is thus 2.050/t m/sec
