A wheel of diameter 0.700 meters rolls without slipping. A point on the top of the wheel moves with a tangential speed of 2.00 m/s with respect to the ground.
1. If the wheel suddenly stops spinning and skis along the ground then
a. v=rù
b. v>rù
c. v<rù
thank you

THE wheel is not spinning, so the point on the top of the wheel is moving at the same speed as the wagon, and angular velocity of course is zero. This is an odd question.

so is it A B OR C

ANGULAR Velocity is zero. Repeat, angular velocity is zero. IS V zero?

and,make certain the question is typed wrong. This is indeed a very odd question.

What do v and ù represent? The dimensions don't even make sense. Putting a dot above a number usually represents a rate of change.

I think the idea is that the final speed of the top of the wheel is less than it was when it was rolling.
