**1. **Aim: How can we approach projectile problems?

**2. **Separate Components Velocity, acceleration, and distance have both horizontal (x) component, and vertical (y) component

**3. **Horizontally Fired Objects Horizontal velocity is constant:

**4. **Vertical Components For the vertical motion, the object is in free fall:

**5. **Projectiles Fired at an Angle Unlike horizontal projectiles, there are both vox and voy
Initial velocity can be resolved into x and y components

**6. **Now what? Since you can determine your vox and voy, the rest we can figure out!!!
Horizontal velocity is still constant
Horizontal acceleration is still zero
Vertical acceleration is -10 m/s2 (just like in vertically fired objects)
Vertical vf at max height is 0 m/s (just like in vertically fired objects)
Vertical displacement is 0 m (the object starts on the ground and ends on the ground)
Time to max height = ½ total time

**7. **Time Vertical and Horizontal time are equal:
