- Vectors: a.) Can you find two vectors with different lengths that have a vector sum of zero?Explain your answer in detail. b.) Can the magnitude of an object’s displacement be larger than the distance it hastraveled? What is the condition for them being equal. Explain your answers in detail.Suppose you walk 15.5m straight west and then 29m straight north as shown in the figure. What is the angle of displacement measured west of north in degrees?You first walk 10 meters at an angle of 30 degrees East of North. Then,you walk 15 meters at an angle of 45 degrees South of East. Assume that East is +x and North is+y, and assume you started at the origin (0,0). A. Make a graph with x- and y-axes and draw your path on that graph (to scale, or at least asclose as you can get). Start the first vector at the origin, and the second vector at the tip ofthe first vector. Then, draw the resultant vector (their sum). B. Break each part of the walk into their x- and y-components and then sum them to get thex- and y-components of the resultant vector. Make sure to include units and unit vectors. C. What is your displacement from where you originally started? D. If the whole walk took 40 seconds, then what was your average velocity
