    You can calculate the centripetal force from [itex]F=m \omega^2 r[/itex].

    How is it possible to calculate the: force that is transferred back to the cowboy, and hence the loses of speed,(off the bull) - assuming that the bull want to move away from the cowboy, (straight) but because of the string it is force to stay in constant orbit ?
