    Initial velocity out of a cannon

    Integral, Yeah our professor did something with the PE and KE, but I couldn't follow him. I copied down what he wrote on the board but i just don't understand it. Here's what he wrote- PE=1/2 kx^2 KE= PE at x=0 KE=1/2 mv^2 PE=1/2(235N/m)(.0635 m)^2 PE=0.48 Nm V=(0.48N m)^2/(0.025) V=6.2...

    Initial velocity out of a cannon

    Hey everyone, I'm doing a lab for engineering class, and I'm having a little trouble with a part of it. The lab was that we have a cannon on a table, with 3 launch settings (different lengths the spring is compressed). The table is 40" high. Also, we have a dixie cup 90" away from the table...

    Gravity with Galileo's inclined plane?

    Doc, I've been talking with my group members, and I found out what my problem was. Since there was so much noise in the class, I misheard the length of the ramp! it was 107.5 inches, instead of 77.5 *d'oh!*. So now that I changed the length, that changes the angle, and so the equations work...

    Gravity with Galileo's inclined plane?

    if I don't square the time, then it comes out to around 11, which is closer, but I thought the times had to be squared... I'll keep looking for things we might be missing, thanks! ~Frank~

    Gravity with Galileo's inclined plane?

    yeah still seems way off to me too... would you mind if I ran my results by you to see if you can pick up where I'm messing up? Our plane was 75.5 inches long, I converted this to 1.938 meters. The plane was also 13.125 inches high, which I converted to .3328 meters. Then, our heavy ball went...

    Gravity with Galileo's inclined plane?

    Whoa Doc Al I have a correction to make, I think I made my graphs wrong, I had distance on the x axis, time on the y axis. When I switch them around and get the slope then, it turns out to be .214, so the acceleration along the incline would be .428, and then the acceleration due to gravity is...

    Gravity with Galileo's inclined plane?

    Doc Al, Thanks a lot for your post! I thought that acceleration due to gravity and acceleration of gravity were different things, but I wasn't sure because my professor is from poland and can't speak english too well lol. How do I get the acceleration along the plane? Is that by taking the...

    Gravity with Galileo's inclined plane?

    Hey everyone, I'm new here, so I'll let you know a little about me. I'm going to uconn right now, and my major is mechanical engineering. I have a question about a lab we did for my engineering class. We replicated Galileo's experiment with inclined planes, and our teacher told us to find...
