1. A robot moved 3m north then turned to the east and moved 5m. a. What is the total distance of the robot. b. Determine the total displacement of the robot. c. The motion of the robot lasted for 60seconds. Calculate the average velocity.
2. A plane travelled 100Km at 60⁰ North of East then changed direction and travelled 250 Km at 30⁰ North of east. a. Determine algebraically the resultant displacement of the plane. Deduce the plane's average velocity if the the time is 55 min. b. Determine geometrically the resultant displacement of the plane.
