Unit 4 Part 2

In the second part of unit 4 we began to learn about angles of trajectory. Using what we learned from part one, we used trigonometry when we were given the initial velocity (hypotenuse) to find the vertical (opposite leg) velocity and horizontal (adjacent leg) velocity. In the picture below, we launched a n air powered rocket into the air and measured its muzzle or initial velocity. We then used that and an angle to predict approximately where the rocket would land. Although our rocket didn't hit its target due to some technical difficulties with our base, i was surprised to see how accurate some of the other student's calculations were.
