Circular Motion... Ok, you have a ball being swung vertically in a circle. Mass=0.1kg, radius=0.8m, speed at top = 6m/s , and this occurs 0.2m off the ground. using the floor as the zero point for gravitational potential energy, what is the total energy. Determine the speed at the lowest...

wow can't believe i didnt think of that...weird

Newton's law problem...have attempted it http://img128.imageshack.us/img128/2941/asd6rh.jpg rope is of negligible mass and no friction...now this is what i did the bc and ab are subscripts for cords between each block 9.8(10)- Tbc = 10a 9.8(40)-Tab = 40a Tab=30a so by...

hmm still kinda confused, any chance you could show me step by step how to solve it like how do you resolve T1 and T2 to get values using components...like i know the 20 has components of x = 0, and y = -20 right? but how do u get values with the 30 degree angle?

i can't remember how to do this at all, but can someone just post a simple step by step solution for this? thanks http://img275.imageshack.us/img275/2392/ss2mx.jpg also having trouble with this one http://img374.imageshack.us/img374/1146/dfsd4mu.jpg

ok, but how exactly do you solve it

yea, I am really not remembering this though lol, just started doing this type of problem
