Question

to get a resultant from combining two vectors in the same direction, you must _. use a parallelogram add subtract use trigonometric functions

Explanation:

When two vectors are in the same direction, to find the resultant vector, we add their magnitudes. The parallelogram method is for non - collinear vectors, subtraction is for vectors acting in opposite directions and trigonometric functions are used for vector resolution or when vectors are at an angle.

Answer:

B. add
