Question

In an assembly operation illustrated in the figure, 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 4.8 cm that lies in an east-west vertical plane. The robot then moves the object upward and to the north, through a quarter of a circle of radius 3.7 cm that lies in a north-south vertical plane.

(a) Find the magnitude of the total displacement of the object.
cm

(b) Find the angle the total displacement makes with the vertical.
?

Explanation / Answer

magnitude of displacement = 10.44 cm and angle = 44.52degrees

see the angle can be either 44.52degrees or 90-44.52 = 45.48degrees depending on where u take the vertical line !
