where b is a constant which you should find.dimensionless mass function. In your solution, use M for the fundamental unit of mass, so that [m] = M, and be sure

to clearly distinguish the three differentт's: m, M, and M.Notation: here, the M is the (c) Solve the dimensionless DE from part (b) and give a qualitative sketch of the solution curve, being sure to indicate the scale on each axis. (d) Find the dimensionful solution m(t) and give a qualitative sketch, being sure againto indicate the scale.
