a toy cart at the end of a string 0.70 m long moves in a circle on a table. The cart has a mass of 2.0 kg and the string has a breaking strength of 40 N. Calculate the maximum speed the cart can attain without breaking the string solution

  • physics -

    Centripetal force = M*V^2/R = 40 N
    Solve for V

    R is the radius im meters and M is the mass in kg.
