A man is trying to swing from a 15 m high cliff on a 12 m long rope. (the rope is horizontal at the start) He let's go when the rope is 30° degrees from the horizontal of the other side. (totaled swung angle is 150°.

How far does he go from the cliff?

Homework Equations


I suppose you would use a circle tangentle speed formula, not too sure.



The Attempt at a Solution



The first part of the problem to calculate the speed of of the launch is where i am having trouble.
