can a resultant external force on a body change its mass but keep velocity of its centre of mass constant ? Is it practically possible -
##\vec{F}_{ext}=\vec{v}_{com}\frac{\mathrm{d} M}{\mathrm{d} t}##
where F is nonzero
##\vec{F}_{ext}=\vec{v}_{com}\frac{\mathrm{d} M}{\mathrm{d} t}##
where F is nonzero
