[Radar Tracking] An airplane is being tracked on a radar n where direction is denoted by angle 0 measured clockwise North. The plane's initial location is given by position vector 20 km from the radar unit at 0 = 30, and its final location is If km at 135. W Sketch a diagram showing the plane's initial and final locations ts displacement vector s . What is the mathematical relation een r , If , and s ? How is this illustrated in your diagram? If the plane travels in a straight line, how far does it travel? this using vector components. [OPTIONAL] Is there another way to solve part (b)? If so, please explain
