Homework Statement:
A wheel is rolling along a road, without slipping or sliding, attached to a car moving with a speed v. A piece of tape is attached to the outer edge of the wheel. When the tape is opposite the road (at the top of the wheel), its speed with respect to the road is
Relevant Equations:
v= vo+at
I initially thought it is v, because the speed shouldn't change when the tape is on top.

How fast is the centre of the wheel moving?
How fast is the tape moving when the wheel has rotated so that the tape is on the road?
