Asked by Aron
A hockey puck that has a mass of 170 g is tied to a light string and spun in a circle of radius 1.35 m (on frictionless ice). The string breaks under a tension that exceeds 5.00 N.
What is the maximum speed of the puck without breaking the string? (Express your answer to three significant figures.)

tension=mass*v^2/r
5=.170*v^2/1.35
v= sqrt(5*1.35/.170)=6,30 m/s check that with your calculator
