Question

Three uniform meter sticks, each of mass M, are placed on the floor as follows: stick 1 lies along the y axis from y = 1.3 to y = 2.3 m, stick 2 lies along the x axis from x = 0.0 to x = 1 m, stick 3 lies along the x axis from x = 1.0 m to x = 2.0 m.

Find the location of the center of mass of the meter sticks.

Answer 1

totalmass*cg=mass1*cm1+mass2*cm2+ ...

cg= 1/3(1.3+.5 +0+.5+1+.5)=1/3(3.8)=..

check my figuring.
