Object A moves along the +x-axis, while Object B moves along the -x-axis. The figure shows the position versus time for both objects. At t = 0, Object A is at x = 0 with a constant speed of 1 m/s (blue line). Object B is initially at x2 =100 m moving at a constant speed of 2 m/s (red line). Determine the position x1 (in meters) where A and B meet.
