Quizplus · Accepted Answer

The velocity of point P' relative to the ground can be found by adding the linear velocity of the center of the wheel to the tangential velocity of point P' on the wheel. Since point P' is at the top of the wheel, its tangential velocity is zero. 
Therefore, the velocity of point P' relative to the ground is simply 11ea7ff9_2b21_efef_a768_2ded29ec7768_TB2295_11, the linear velocity of the center of the wheel. 
Choice C matches this value.
