Q1. You are to program a robotic arm on the assembly line to move in a xy-plane. Its first displacement is; its second displacement is, of magnitude 6.51 and direction 62.7 measured in the sense from +x-axis toward -y-axis. The resultant of the two displacements must also have a magnitude of 6.41, but a direction 22.6 measured in the sense from the +x-axis toward the +y-axis.
