Your dog is running around the grass in your back yard. He undergoes successive displacements 3.56 m south, 8.52 m northeast, and 15.4 m west. What is the resultant displacement? (Take the +x direction to be east.) 8.45 X magnitude Your response differs from the correct answer by more than 10%. Double check your calculations. m direction Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully.° counterclockwise from the +x direction
