1. The problem statement, all variables and given/known data Hey all. Below is the question and picture related to it. "Three uniform metre sticks each of mass M are attached together as follows: Stick 1 lies along the y axis from y = 0 to y = 1.0m. Stick 2 lies along the x axis from x = 0 to x = 1.0m. Stick 3 makes an angle of 60 degrees with the y axis. Find the x and Y coordinates of the centre of mass of the system of three metre sticks, and marks its approximate location on the diagram of the three sticks." ----Sorry, its kinda upside down :) 2. Relevant equations 3. The attempt at a solution I am really confused with this one. Maybe lets start with the X The formula I know is: Xcm = m1x1 + m2x2 + m3x3 / m1+m2+m3 But how do I input into this formula... ??
