1. Non-horizontally Launched Projectiles  A falling ball can start by heading upward!  Velocity starts in the upward direction  Velocity becomes less and less upward  Altitude increases at an ever slower rate  At some point, vertical velocity is momentarily zero  This is called the peak  Vertical velocity becomes more and more downward  Altitude decreases at ever faster rate

5. Consider the launch velocity vector: a) The launch angle is given. b) The components can be drawn. c) The components can be expressed in terms of the launch angle.

6. Various paths taken by a projectile launched at 300 m/s at Note that the 45-deg launch yields the greatest distance.
