ssm 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 string rotates at an angular speed of 56 rev/s, and its tip has a tangential speed of 60 m/s. What is the length of the rotating string?
in m

  • physics - ,

    Vt=rw
    r=Vt/w
    so:
    r = 60m/s÷[56rev/s(2πrad/1rev)
    r=0.17 m
