projectile motion, video 4, working several type 2 problems

In this video that I put together for my physics students, I work several projectile problems. The ones I work on this video represent what I call 'type 2' trajectories. These are projectiles that begin and end at the same place vertically. For example, ground to ground. These type 2 projectiles make full, symmetric parabolas in terms of their trajectories. I work two problems and use a note packet I put together for my students they can use while they watch the video.
