Mathcad prime 9.0
This is quite a lot to look at, but I'm struggling with getting this graph as well as the following two to accept my values. I'm relatively new to Mathcad, so any tips would be more than appreciated.
ive tried expanding my values to use less variables, but nothings seems to help this issue.

According your problem that some functions, which were derived via symbolic evaluation, are considered "not defined" when later used numerically:
The cause is that with the symbolic evaluation the units loose their label "Unit" and are treated as unknown variables and so a later numeric evaluation fails.
To cope with this problem PTC has implemented the option "Units/Constants in Symbolics" in the Calculation Options.
You should turn on this option and then recalculate the worksheet.
Actually I don't understand why this option is not turned on per default.
Your unit problem is based an the fact, that your parameter t is used dimensionless and not as dimension time.
That way integration over t does not change the unit and your velocity and displacement are still of dimension acceleration.
You may correct this by multiplying the definition of v and S by seconds (see attached worksheet), but IMHO the better approach would be to use t as time throughout which also means that you would have to write something like sin(t/s) instead of sin(t) or sin (omega t) with omega as frequency.
