suppose you took a 3m long piece of the fishing line discussed ( the line has a test strength of 125lbs) attached a 2.5 kg ball to the end, and spun it overhead. at what speed of the moving ball would the line break?

  • physics -

    test strength=mv^2/r

    556N=2.5*v^2/3

    solve for v

    how did I convert lbs force to N?
    1 pounds is equal to 4.4482216 newton.
    125*4.45=556N
