1. The problem statement, all variables and given/known data A big olive (m = 0.051 kg) lies at the origin of an xy coordinate system, and a big Brazil nut (M = 0.56 kg) lies at the point (0.81, 3.0) m. At t = 0, a force Fo = (2.6 + 1.7) N begins to act on the olive, and a force Fn = (-4.4 -3.4) N begins to act on the nut. 2. Relevant equations What is the (a)x and (b)y displacement of the center of mass of the olive-nut system at t = 5.6 s, with respect to its position at t = 0? 3. The attempt at a solution Okay, so far, I found X center of mass, and Y center of mass. (0.742,2.75) I don't know what to do afterwards. I tried combining the forces, resulting in a Fnetx and Fnety. So... now... me lost >.< Can someone give me a little help please.
