1. The problem statement, all variables and given/known data A 0.50-kg ball, attached to the end of a horizontal cord, is rotated in a circle on a frictionless horizontal surface. The chord will break if the tension exceeds 50N, so there is a maximum velocity for the ball. However, if there was friction on the surface, would the maximum velocity be affected? 2. Relevant equations Fn (u) = Ff 3. The attempt at a solution I think if there was friction, the friction would pull the ball in more, thus lessening the tension in the string which increases the maximum velocity. However, wouldn't there be tangential friction as well?
