3. You are going for a walk in a flat, grassy field and undergo three successive displacements as follows: Ař, has a magnitude of 35 m and is due West, Ai, has a magnitude of 47.5 m and is directed at 25° West of North and Ar, has a magnitude of 25 m and is directed at 38° South of West. You then want to undergo a fourth displacement, Ar,which takes you right back to your starting point.

Transcribed Image Text:3. You are going for a walk in a flat, grassy field and undergo three successive displacements as follows: Ar, has a
magnitude of 35 m and is due West, Ař, has a magnitude of 47.5 m and is directed at 25° West of North and Ar, has a
magnitude of 25 m and is directed at 38° South of West. You then want to undergo a fourth displacement, Ar,which
takes you right back to your starting point.
a) Draw a rough sketch showing how to determine Ař, graphically
b) Calculate Af, using the method of components. Express your final answer in magnitude / direction form.
