in the vertical, tension at the bottom is mg+mv^2/r
In the horizontal, tension is mv^2/r
1.18 mv^2/r=mg+mv^2/r
solve for v
How do u know the mass?
Mass does not matter. Notice mass divides out. divide both sides of the equation by m.
What did u you get as the answer.. i have a feeling mine is wrong
I can't divide out the v's and I know you are solving for "v".. but I can't seem to finish it out..
I got...
8.1v^2=mg+mv^2/r Then
8.1v^2=g + v^2/.45
then I don't know what to do from there
