Jump Around
Whenever my cousins and I are together, we tend to get a little insane. On our recent family trip to Pennsylvania, we decided to jump off the ledge of a nearby bench. Each jump, we tried to land on a manhole about 5 feet away. Not only did it make for a great picture, but also demonstrated falling at an angle. This is one element of projectile motion we learned about. Remember the rolling ball lab? Yeah, that thing that we learned about two weeks ago. To figure out the exact spot something will hit when it is falling at an angle, we have to calculate both the vertical and horizontal distances and velocities. Think of it as an equation. Say the bench was 2 feet tall and we were jumping at a velocity of 5m/s. How long would it take me and my cousins to reach the manhole? Think you can figure it out?
