Suppose a balloon of constant mass M contains a bag of sand of mass Mo experiences a constant force upward thurst C. Initially it is in equilibrium and that sand is released at a constant rate a(alpha), so that all of it is released in time to, set up equation of motion for Balloon.

Step 1

Consider the total mass(balloon+sand) of the system is denoted by *M’* (*M+M0*) and it experien...
