Yeah meters. All in all what I'm trying to figure out is this. You have the equation y(t)= -sin(x(t)), and there is a sled at the origin with John on it being pushed at 5 m/s by Mary. There is no friction, he weighs 1 kg and the sled weighs nothing, and she stops pushing at the bottom of the...

woah that's a lot haha... uh what is the correct equation for arc length? i know I'm close with ds = intrgl sqrt(1 + (dy/dx)) ^2 dt, but i can't quite finish haha. then how do i find the v in there? I'm really confused sorry xD

Plus she also stops pushing at the bottom of the hill

I think the standstill thing wasn't right. Thanks for responding! Uhm, how do i know the velocity of the sled at the inflection point? How would i calculate that?

I didn't notice the guy who responded but thank you haha.

Homework Statement Well instead of asking the entire question, I just would like some help getting started. What equations, or even some lesson plans/examples, are out there that can help me with finding things like velocity, distance moved, force, etc on something that moves along a sin...

Also, I don't know if this belongs here D: Sorry if it doesn't!

Homework Statement We are trying to solve a problem where, we'll call him John, is being pushed down the hill too fast by Mary and when he goes back up the next hill he ends up flying up off the ground. We are trying to solve where, on the graph (coordinates) he lands. Here is what I know...
