							To solve these type of problems you should have a basic knowledge of differentiation and integration.It usually depends on the question asked . You can usually start with basic equation of $F = \frac{\partial p}{\partial t}$Then dp = d(mass x velocity) = v dm +m dvThere are many ways to approach a problem.If you have any specific question to ask I can help. The term force thrust is mostly used for the force exerted on the body by the mass leaving the body like gases leaving the exhaust of a rocket during propulsion.It can be stated as in form of equation above. $Fthrust = v \frac{dm}{dt}$where v = velocity of the mass leaving(dm) relative to the body.Usually the equation is $F_{thrust} + F_{external} = m a_{com}$where a is acceleration of centre of mass of the body.
