Variable-mass system events. The following derivation is for a body that is gaining mass (accretion). A body of time-varying mass "m" moves at a velocity v at an initial time "t". In the same instant, a particle of mass dm moves with velocity u. The initial momentum can be written as Now at a time "t" + d"t", let both the main body and the particle accrete into a body of velocity v + dv. Thus the new momentum of the system can be written as Since d"m"dv is the product of two small values, it can be ignored, meaning during d"t"
Landscape of the Body it to us. It informs our understanding of the playwright we know best in terms of his masterpieces, 'Six Degrees of Separation' and 'House of Blue Leaves'. But 'Landscape of the Body' deserves better than it gets here." Landscape of the Body Landscape of the Body is a two-act play by John Guare, first performed in 1977. The play is episodic and non-linear, as it travels back and forth in time. The plot centers on a woman named Betty, whose son, Bert, was recently murdered and decapitated in lower Manhattan. The location of the first and last scenes are the
