Another physics question for all you smart people out there
A 0.50-kg ball that is tied to the end of a 1.5-m light cord is revolved in a horizontal plane with the cord making a certain degree with the vertical. If the ball is moving at 4.0 m/s, how can I find the angle that the cord makes with the vertical?
This one is a toughie!
I worked on this a couple of hours, but I keep on running into the same dead ends, could anyone give us some pointers?
(This is the direction I've been trying to go with no luck)
Fx = Tsin(theta) = m((v^2)/r)
Fy = Tcos(theta) - Fg = 0
