A 0.80-kg ball, attached to the end of a horizontal cord, is rotated in a circle of radius 1.7 m on a frictionless horizontal surface.If the cord will break when the tension in it exceeds 90 N, what is the maximum speed the ball can have?
Express your answer using two significant figures.

M V^2/R = Tmax = 90 N

Solve for V
M = 0.80 kg
R = 1.7 m
