It's probably really easy, but I can't figure it out. It's actually a two-part question where I also need to find the radius of curvature, but that one I can solve once I know dy/dx by using the arc length and identifying with in the acceleration that we know.
Perhaps not exactly. But you could get it correct to first order, perhaps. That might be good enough.I can't integrate it to get the velocity.
Question: how do you interpret the phrase "constant velocity "? Do you think that for all time? Do you also think that initially, the ball is moving only in the x direction with speed
