Calculate , where . Also determine the direction of the resulting vector.
, Direction is away from .
, Direction is away from .
, Direction is the same as .
, Direction is away from .
, Direction is the same as .
, Direction is away from .
In order to solve the first part of the problem, we need to remember how to take the magnitude of a vector and scalar.
, where is a scalar.
Now lets calculate this.
As for the direction of the vector, since , the resulting vector will be against the original vector .
