Calculating Friction Force to Stop a Rolling Ball

[kristy_vincen]

The question is BASICALLY: A ball is rolling on a cement floor (accelerating). Determine the friction force required to stop the ball.

Of course it gives you the weight and speed of the ball, and I believe i know the answer. I just want to check it.

If I figure out the magnitude of of kinetic force, would it not take the same amount of friction force to stop the ball? So the kinetic force = friction force?

Thank you
