A child of mass 22 kg swings at the end of an elastic cord. At the bottom of the swing, the child's velocity is horizontal, and the speed is 6 m/s. At this instant the cord is 3.70 m long.
At this instant, what is the perpendicular component of the rate of change of the child's momentum?
someone please help i know that the perpendicular component is 0
mv^2/r
i tried 22*6^s divded by 3.70
and got 214.05. but its wrong can someone help me please thanks!
