SUMMARY

To make vector A = a(3.0i + 4.0j) a unit vector, the constant 'a' must be determined such that the magnitude of vector A equals one. The correct value of 'a' is 1/5, as this ensures that the magnitude of the vector is normalized to one. This conclusion is based on the definition of a unit vector, which requires a magnitude of exactly one.

Homework Statement



If vector A = a( 3.0i + 4.0j) , where a is a constant, determine the value of a that makes A a unit vector.

Homework Equations




The Attempt at a Solution



I thought the answer is 1/5, since a unit vector has a magnitude of one therefore you need to divide it so that the magnitude of the vector equal to one.
