No, it's on an assignment... mu=Mm/(M+m) and l is the magnitude of the angular momentum. I can use l since the direction of L is constant as it's only in one plane - yes?
Homework Statement
The problem involves two particles of masses m and M; initially, m is at r=∞ and has a velocity v=v_o. The path of m is deflected, ie pulled towards M due to its gravitational pull.
Question: Find the mass M (in terms of the quantities given) at a distance d where the...
