The string of a certain yo-yo is 80 cm long and will break when the force on it is 10 N. What is the highest speed the 200 g yo-yo can have when it is being whirled in a circle? Ignore the gravitational pull of the earth on the yo-yo.

  • Physical Science - ,

    M V ^2/R = 10 N.

    R = 0.8 m
    M = 0.200 kg
    Solve for V, in m/s.

    Okay, so would I solve it like:

    v^2=.8/.200 ?

  • Physical Science - ,

    1.5 m/s
