Hello,
Whenever I use a unit such as Newton or velocity.... anything that has a "per second", MathCad multiplies it incorrectly. If I type out m*sec^-1 it works. Why is this and how do I fix it? It is very cumbersome when working with lbf and newtons.
You don't have W defined as a weight. You have it defined as a dimensionless quantity, which is not a weight.
Are you saying the quadratic is
where x=v^2? Where did this come from? Either the units in all the terms must match, or it is empirical (i.e. not derived from physics, but calculated by fitting a quadratic to measured data). Or, of course, it could just be wrong. Is this an empirical formula?
In the Mathcad worksheet it says "Problem 6", and I assume this is the answer. In which case it might help if you posted the problem.
