In this problem, we'll perform vector addition and subtraction and determine vector magnitude.
2D vector Magnitude:
Consider two vectors A and B. expressed in unit vector notation as A = a1i + a2j and B = b1i + b2j.
Part (a). Enter an expression for the vector sum A + B in terms of quantities shown in the expressions above.
Part (b). Enter an expression for the difference vector A - B in terms of quantities shown in the expressions above
Part (c). Enter an expression for the square of the magnitude of the sum vector | A + B | in terms of quantities shown in the expressions above.
