A bowling ball hangs from a rope with length L of 5.00 meters. Initially, the bowling ball is at a position such that the rope makes a 20 degree angle with respect to vertical. The ball is released from rest. What is the speed of the bowling ball when it swings down and the rope makes an angle of 10 degrees? Just looking for help on setting the problem up. I have done every other problem on my homework so far with relative ease. I'm sure I've learned what I need to know to do this problem, but it's just not happening Whoever can point me in the right direction, the chapters are all focused on Newton's 2nd law, and thus any responses should be pretty basic It's just a physics I class, but my book has no pendelum problems in it for examples thus far.
