## Homework Statement

a thin uniform wire is bent to form two equal sides AB and AC of triangle ABC , where AB=AC=5cm . the third side BC , of length 6cm is made from uniform wire of twice the density of the first . the distance of centre of mass from A is ?

## Homework Equations

x

_{centre of mass}= m1R1+m2r2/ sum of masses(where r= centre of mass of particle in sys.)

λ=m/l ( where m= mass of object , l=length ) uniform density formula

## The Attempt at a Solution

i was able to calculate the X c.o.m which is = 12λ*lenght of rod BC/2

but was unable to calculate its y coordinate ?
