I need some uinspiration for a physics project concerning projectile motion. Our group needs to design and build a device that will launch an object a considerable distance (say, 50-100 yds), can be adjusted to shoot on an angle or horizontally, and maintains a fairly constant initial velocity...
Okay...I THINK I have it. For some reason my brain is not grasping this concept as readily as it should. Perhaps I just need to pound it in a little more. :) Thanks for your help!
I'm not looking for instant answers, I really need this explained. I absolutely hate having only partial knowledge of a concept...it always messes you up in the end.
First time posting here. . .
Okay, usually I'm pretty good figuring these type of questions out, but the textbook just doesn't help(no e.g.'s or explanations) and the teacher didn't talk at all about static friction, so, if anyone could give me a hand, I'd be very grateful.
Question:
A sled...
