An оbject mоves in the XY-plаne. It stаrts by mоving 40 cm аt 50o counterclockwise relative to the positive x-axis. Then it moves 70 cm at 65o counterclockwise relative to the positive y-axis. Finally, it moves 30 cm at 35o clockwise from relative to the negative y-axis. (a) Calculate the magnitude of the resultant displacement.(b) Calculate the direction of the resultant displacement, represented as an angle measured counterclockwise from the positive x-axis.(c) If the whole journey took 7 seconds, calculate both the average speed and the average velocity of the object.
