2.  Now we have movement in both x & y dirs.  Gravity acts down  v y changes  No force horizontally  v x is constant

3. 1. Separate everything into x & y columns  only time can pass between the columns  a = -9.8 m/s 2 in y-direction 2. Write all givens in correct columns  separate v o into v ox and v oy 3. Write equations  3 Amigos in the y-direction  v=Δs/t in the x-direction 4. Solve

4. A cannon is fired with v o = 40 m/s at a 30° upward angle. How far away does it land? vovo θ ____x_______y___

5. A cannon is fired with v o = 40 m/s at a 30° upward angle. How far away does it land? vovo θ ____x_______y___

6.  Horizontal projectiles have θ = 0°  At the peak, v y = 0  If it starts and ends at the same level:  v fy = -v oy  Δy = 0  at the peak t = ½ the total travel time  v ox = v fx = v x everywhere
