Centripetal acceleration using a sling

  1. Sep 14, 2010 #1
    1. The problem statement, all variables and given/known data
    You plan to throw stones by using a sling of length 1.6 m which you whirl over your head. Suppose you wish to throw a stone a distance of 32 m. What must be the centripetal acceleration of the stone just before its release if it is to reach this distance? Assume that the release height is 2.4 m.


    2. Relevant equations
    Ay=v2/R


    3. The attempt at a solution
    Attempted to use kinematic and 2 dimensional equations but cannot find a way to get a velocity or a time to figure anything out

    any help would be great thanks!

    How long does it take to fall 2.4m?
    What velocity does it take to travel 32m in this time?
    What centripetal acceleration do you need to get this tangential velocity?
