It was part of my free body diagram I came up with, I assume I did it wrong. mg would still be there right? Would I use a cos20 and sin20 in some equations?
Homework Statement
A .30kg ball is swung in a conical pendulum whose length is 95cm. If the string makes an angle of 22 degrees with the vertical, what are (a) the balls speed and (b) the tension in the string

Homework Statement
A person whirls a ball and string in a vertical circle of radius 1.50m. The ball travels at a constant speed of 6.50 m/s around the circular path; its mass is 55.0g. What is the tension in the string at (a) the bottom and (b) the top.

I'm having a really hard time figuring out where to start this problem, let alone finish it. Can anyone help me through it? I attached a scanned picture of the problem.
Thanks,

I don't believe we need to use tensions. we used a force plate and just had to make the third pulley and its hanger/mass into equilibrium. Thats gives 3 degree's and 3 masses's. for each problem which there are 5 different sets. So we just with fnetx and fnety for the 3 degree's and 3 masses...
Homework Statement
The question is: find the vector sum of the tensions in the strings; remember to multiply each mass by g. In theory, this sum should be the zero vector.
We had to use pulleys and weights and find the angle and mass of a third hanger to make a ring in the middle of a...
