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:
