Need help with this probelm not with the maths involved but the theory,
Wheel radius R rolls to the right along straight line with speed v, the path of a point on the rim is given by;
c(t)= ( vt - Rsin((vt)/R) , R-Rcos((vt)/R) )
When is the velocity vector of this point horizontal and what is the speed at this point?
Trying To work out when velocity is horizontal?
