    Elastic and Inelastic Collision

    *No, I am saying your formula is wrong. With similar masses, it gives a good approximation, but it is still wrong.* -I'm lost here! >.< *"Slow down" is not related to the impact itself (where it certainly does not slow down!), so the mass difference has nothing to do with anything happening...

    Elastic and Inelastic Collision

    clarification *Where do the numbers come from then?* - hahaha sorry. I meant we did not measure the velocity after pushing it. :) hahaha that is how the setup seemed like. the incident cart was a little bit farther in OUR setup. :) *This would require m1=m2. As the masses are similar, the...

    Elastic and Inelastic Collision

    Our professor assisted us during the experiment. In experiment 2, we did not measure the velocity of the incident cart anymore and our prof gave us this equation. I think he was assuming that the incident cart will stop after the collision. (Does this make any difference?) *Are you sure that...

    Elastic and Inelastic Collision

    These are the instructions: What to do: 1. Connect the two photogates to DIG 1 and DIG 2 ports of the LabQuest device. Connect this device to a computer and turn on the device. 2. Open Logger Pro 3.8.4 software. Click Folder icon/symbol. Open Probes & Sensors > Photogates > Two Gate Timing. 3...

    IMPACT FORCE of a ball in an inclined plane

    Thank you Hello po! Thank you for this! we have an experiment, The setup looks like the attach file. The metal elbow track isn't on a table or anything it is hanging on the iron stand with the help of the clamps and all. then as we released the ball, the metal track tilted. We are suppose to...

    IMPACT FORCE of a ball in an inclined plane

    [b]1. What would be the effect on the impact force of a lower or higher release point of a metal ball in an inclined plane. [b]2. I don't know what to do here.. or how to answer. My teacher told us to include formulas to prove our answers.
