Vector a is 2. 80 cm long and is 60. 0° above the x-axis in the first quadrant. Vector b is 1. 90 cm long and is 60. 0° below the x-axis in the fourth quadrant. Use components to find the magnitude and direction of a) a+b; b) a-b; c) b-a. In each case, sketch the vector addition or subtraction and show that your numerical answers are in qualitative agreement with your sketch.

James needs to move this box. he has already checked it and knows it is not too heavy for him to lift. he also has a clear path and a place to safely set down the box. tell james what to do next to safely lift this box by placing the steps in the correct order. place the options on the left in the correct sequence by dragging them to the appropriate answer box to check your answer.
