1. The problem statement, all variables and given/known data I'm doing project using xsens MTi-G. Data file example: I must plot motion in plane (decart coordinate system), without z component. Measurment is taken after 0.01 s. To do the task, I should use acceleration and velosity data. 2. Relevant equations 3. The attempt at a solution Can I use those equations? I guess they are for constant acceleration. Or am I wrong?
