Variable-mass system the momentum of the system varies for Therefore, by Newton's second law Noting that u - v is the velocity of d"m" relative to "m", symbolized as v, this final equation can be arranged as In a system where mass is being ejected or ablated from a main body, the derivation is slightly different. At time "t", let a mass "m" travel at a velocity v, meaning the initial momentum of the system is Since the main body will be losing mass, d"m" will be negative, meaning that at a time "t" + d"t" the momentum of the system becomes
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
