Answer» Man goes 50 m to North , then 40 m to East and 20 due South. We NEED to find out the displacement of the whole journey.First of all , we need to define Displacement :Displacement is the shortest length between the starting and stopping point. It's a vector having both directions and magnitude.Look.at the attached diagram to UNDERSTAND his trajectory from home to field.So the diagram SHOWS a Trapezium like figure which is formed in his journey . We need to find x.Thos can be done using Pythagoras theorem:So displacement is 50 m |
