Question
The force table consists of a circular platform with markings at the edge showing the angle for a circle centered about the center of the table. A mass, m = 135 grams is placed on a hanger which has a mass of 50 g, giving a total mass of 185 g. The hanger is then hung at an angle of 140 degrees over a pulley attached to the force table by using a string of negligible mass.
a) What is the tension, F, in the string? (Note: the tension is equal to the weight, W = mg, of the mass)
b) What are the components of the vector F? The +x and +y axes are at 0 degrees and at 90 degrees respectively. (Fx = ?, Fy = ?)

(Fx = ?, Fy = ?)Explanation / Answer
F = m*g = 0.185 kg * 9.81 m/s^2 = 1.81485 N
Fx = F * cos ? = 1.81485 N * cos 140 = -1.39 N
Fy = F * sin ? = 1.81485 N * sin 140 = 1.16656 N
