(a) With the help of a mathematical expression, distinguish between momentum-of- momentum and angular momentum. (b) How do you affect the rate of change of momentum-of-momentum in terms of (i) direction and (ii) magnitude? Answer with mathematical expression. (c) Distinguish between impulse and torsional impulse. Explain their utility in the context of affecting spacecraft dynamics.
