    why would it be needed? also $$\frac{v+w}{u}$$ is supposed to be the distance between C and B if we take everything from the perspective of w

    yes i meant $$\frac{v+w}{u}$$

    Why Was My Thread Closed on the Physics Forum?

    what i tried to do is solve it using the point of reference of w so i get that AB is tilted to the left at an angle a and that CB would be v+w but the solution says it sould be v+w/u and that i should use the formula above to find a and hence find the time but i dont understand why

    B Jaan Kalda kinematics -- Radius of Curvature of a Cycloid

    why would the curve of the point be flatter than the curve of the wheel? edit: i think i get it now

    B Jaan Kalda kinematics -- Radius of Curvature of a Cycloid

    Cycloid is a curve which can be defined as a trajectory of a point marked on the rim of a rolling wheel or radius R. Determine the curvature radius of such curve at its highest point. what you need to do is to equate 4v²/r with v²/R and to get that r=4R but i dont understand why the answer...
