Homework Statement
17. A 100 g bead is free to slide along an 80 cm long piece
of string ABC. The ends of the string are attached to a
vertical pole at A and C, which are 40 cm apart. When
the pole is rotated about its axis, AB becomes
horizontal.
a. Find the tension in the string.
b. Find the speed of the bead at B.
Homework Equations
F=ma
a=v^2/r
The Attempt at a Solution
Using X^2 + (40)^2 = (80 - x )^2, I got 30 and 50 for the lengths of the two parts of the string. Now I am stuck on how to break the Forces into x and y components.
