x= -11+9t+11t^2

y= -23-21t

z= -93+25t+11t^2

What is the magnitude of the objects acceleration at t= 3.00s?

Would I add the second derivatives for magnitude?

You mean |a| = x'' + y'' + z'' ?

Nooo …

Acceleration is a vector (just like velocity ).

So its magnitude is calculated from its components the same way as for any vector.
