Question1
In an assembly operation a robot moves an object first straight upward and then also to the east, around an arc forming one-quarter of a circle of radius 4.80cm that lies in an east-west vertical plane. The robot then moves object upward and to the north, through one-quarter of a circle of radius 3.70cm that lies in a north-south vertical plane. Find out-
(a) The magnitude of total displacement of the object
(b) The angle total displacement makes with the vertical.
Question2
