Hi, so confused abou this question that I probably haven't even posted it in the correct section.Here's the question.
A wheel of radius ,r, is situated at the top of a ramp having an angle θ = π/6 rad. At t= 0 the wheel is at rest with its centre at coordinates (0,r) and then it starts to rotate clockwise, without slipping, in the positive x direction with constant angular velocity ω.
Find the parametric equations of the x and y coordinates of the point p (green dot on graph) with respect to the t >= 0, assuming the initial co-ordinates are at (0, 2r).
I think possibly ω=ω+at but I don't even know what is going on. If it helps in anyway I know the circle has centre (0, r) radius r so the equation would be x^2 + (y-r)^2 = r^2
The Attempt at a Solution
The reason I'm so confused is that I'm sure they haven't taught us this work yet. I think I do it by working out the parabola motion of p then split that into equations for the horizontal and vertical motion, but literally no idea how I would even go about doing that let alone writting it down mathematically. ANY help would be great. Thanks.
