    Undergrad Calculating sling projectile speed from video.

    Hmm I was able to hear the snap/crack? Low volume? And again that's the thing that's astonishing to me, ~340 m/s is the speed of sound, which would make 3620 m/s over mach 10? O_o'

    Undergrad Calculating sling projectile speed from video.

    That's pretty crazy... Even if we keep with the conservative 3620 meters/sec^2 figure...I have to wonder how many firearms could shoot projectiles at that speed within the same distance. That's why I'm having such a hard time digesting this figure. It seems astounding, but maybe I'm simply...

    Undergrad Calculating sling projectile speed from video.

    https://www.youtube.com/watch?v=6IQ15ymhR2M This clip from the history channel as is titled, attempts to address the likelihood of David killing Goliath with a sling. As you can see in the video, the pro Slinger when testing the force on a load cell, got a reading of 3.62 kN or 3620 N...

    High School How fast would an object have to be moving to

    Dave your assumption was more or less correct, that is the visual that I am imagining.

    High School How fast would an object have to be moving to

    I am indeed sort of thinking of it from a visual of a person running up a wall. But more specifically the scale of the question I'm visualizing is rather impossible, in which the person can somehow keep going without ever completely losing their horizontal acceleration--or at least for a...

    High School How fast would an object have to be moving to

    Suppose, its a 100 foot wall?

    High School How fast would an object have to be moving to

    Sorry, how fast would an object(let's say a human like object for simplicities' sake), theoretically have to be to overcome gravity and run up a vertical surface like a wall?

    High School How fast would an object have to be moving to

    move up a vertical surface with no interruption? I've seen this represented so many times in various fictional media, that I'm curious if there is some real life phenomena from which it draws inspiration? There are probably factors such as the size of object involved surely? Anyway...
