Try again. A string trimmer is a tool for cutting grass and weeds; it utilizes a length of nylon "string that rotates about an axis perpendicular to one end of the string. The 52 m/s. What is the length of the rotating string? rotates at an angular s peed of 36 rev/s, and its tip has a tangential speed of the tolerance is +/-2% LINK TO TEXT By instructor Question Attempts: Unlimited SAVE FOR LATERSUBKET ANSWER

Explanation / Answer

relation between linear speed and angular speed is

v = r*w

given w = 36 rev/s = 36*2*3.14 rad/s

w = 226.08 rad/s

r = 52/226.08 = 0.23 m
