Question


Two vectors A and B are shown in the x-y plane. Vector A has a magnitude of 5.0 m and makes an angle of 55.0½ with the positive x-axis vector B has a magnitude of 2.0 m and makes an angle of 33.0½ with the negative x-axis. (See the figure above.) Vector C (not shown in the diagram) is the difference of A and B (C = A - B). If you enter an expression, use degrees as arguments for sin and cos, rather than radians. What is the magnitude of C? |C| = image showing a longer vector A pointing up and right and a shorter vector B pointing up and left

Explanation / Answer

The two vectors are tail to tail so that'll give us C = A - B so C is the vector from the head of B to the head of A The angle between vector A and vector B is 90
