A vector of magnitude 15.2 directed along the positive $x$-axis combines with a second vector of magnitude 14.8 and unspecified direction. What is the minimum possible magnitude of the resultant total vector?
A) 14.8
B) 3.5
C) Not enough information is given.
D) 21.2
E) 15.0
F) 0.4

Question

Quizplus · Accepted Answer

The minimum possible magnitude occurs when the second vector is directed opposite to the first vector, resulting in a subtraction of magnitudes: $15.2 - 14.8 = 0.4$.
