1. The problem statement, all variables and given/known data http://i829.photobucket.com/albums/zz219/fuzzy1233/p.png 2. Relevant equations Fnet=ma=mv^2/r Fg=mg 3. The attempt at a solution Since sides length 3,4 and 5m are given and is in a right angle, I can solve for the angle between 5 and 3 (53.1 degrees) and between 5 and 4 (37 degrees). Then with the angle and a side (3 or 4), I solve for the x component, r, which is found to be 2.41m. Since the 4m rope is given to be 22N, I use trig and solve for the x component of force and found it to be 13.23 N. I then use Fnet=mv^2/r Fx?=mv^2/r 13.23N=(1.3kg)v^2/2.41 v= 4.9 m/s edit: I got 5.8 m/s this time and I believe that could be correct. For the total Fx, I added the two x components of the tensions that I solved using trig. I am not sure if this is right and need verification. Thanks!
