Re: 6 feet deep; scalar or vector?

6 feet is scalar but deep implies a direction ie downwards so that makes it a vector.

If you were standing in a trench, 6 feet deep, and you fired an arrow upwards you'd have to use the equations of motion to determine what happens next. Those equations use vector quantities, ( except time).
