What is the displacement of a point on the wheel of radius R initially in contact with ground when the wheel rolls forward half a revolution?

Given,

Radius of the wheel = R

When half revolution is made by the wheel, the point of contact moves from point A to C and hence undegoes the displacement

Distance displaced by the point of contact, AB =

Perpendicular distance traversed by the body = 2R

Therefore, total distance,

and

Thus the point of contact undergoes the displacement of magnitude  making an angle  with the ground.
