In order t o obtain the equations of motion of the rocket, the following procedure is used. An arbitrary but fixed instant of time is considered. A fictitious solid body is denoted by S with mass m, which would be obtained if the rocket at the instant t solidified and ceased giving off particles. The solid body S will not be homogeneous; in some of its parts, it will have the density of a metal and in other parts the density of a gas, and so forth. It shall be assumed that the fictitious solid body S is invariably fixed to the body of the rocket and from the instant t onwards (instant of solidification) moves together with the rocket. The momentum of the body S shall be denoted by Q.\u003c\/p\u003e","brand":"Bibliogov","offers":[{"title":"Paperback","offer_id":47596365578391,"sku":"9781287246961","price":1339.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/3471\/1191\/files\/9781287246961.webp?v=1774993486","url":"https:\/\/atlanticbooks.com\/products\/equations-of-motion-of-a-rocket-9781287246961","provider":"Atlantic Books","version":"1.0","type":"link"}
