Question

Describe th system of veriable mass an roket propulsion

Answer 1

In mechanics a variable-mass system is a collection of matterwhose mass varies with time. It can be confusing to try to apply Newton's second law of motion directly to such a system.Instead, the time dependence of the mass m can be calculated by rearranging Newton's second law and adding a term to account for the momentum carried by mass entering or leaving the system.
