A 64.8 g drink is left on a turntable causing it to turn with an angular speed of 8.50 rad/s. If the drink has coefficients of friction of μs = 0.890 and μk = 0.500 with the turntable, what is the furthest distance that the drink could have been placed from the centre of the turntable for the drink not to slide?

  1. the mass is not a factor

    (8.5 * r)^2 / r = .89 g

    r = .89 g / (8.5^2)
