Question

You are to program a robotic arm on an assembly line to move in the xy-plane. Its first displacement is A? ; its second displacement is B? , of magnitude

6.37cm and direction 62.9? measured in the sense from the +x-axis toward the -y-axis. The resultant C? =A? +B? of the two displacements should also have a magnitude of 6.37cm , but a direction 21.5? measured in the sense from the +x-axis toward the +y-axis.

Find the component Ax of A?

Find the component Ay of A? .

Find the magnitude of A.

Find the direction of A? measured in the sense from +x - axis toward the +y - axis.

Explanation / Answer

Solution: Given, magnitude of B = 6.37 and directed 62.9
