## 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 Im stuck on how to break the Forces into x and y components.
