In the above problem, if the cyclist reaches exactly the other side of the point\[x\](i.e. diametrically opposite point to \[x\]), then find the distance travel led and magnitude of displacement of cyclist.

Answer:

Distance covered = Half of the circumference of circle\[=\frac{1}{2}\times 2\pi r=\pi r\] Initial position = x, Final position = y Magnitude of displacement\[xy=?\] From figure\[xy=xo+oy=r+r=2r.\]
