A string 1.5 m long breaks when its tension is 100 N.
a. What is the greatest speed with which the ball can be moved around a horizontal circle if the ball has a mass of 2 kg?
b. Find the speed for the same setup, but for a vertical circle.

  • Physics -

    In a vertical circle, max tension is at the bottom.

    Tension=mg+mv^2/r

    solve for v

    In a hoizontal circle, tension is more complicated.

    Tension=m * sqrt((v^2/r)^2+g^2)
