    Note for my future reference :
    DONT YOU DARE FORGET THE FORMULAE! exam ke time panic karogi derivation ni ho payega
    r com = Sigma mi ri/ Sigma mi ( can work for ∆ displacements as well)
    Here, for continuous distributions: Integration r dm/ integration dm
    You can differentiate too to get v com , a com
    V v imp point
    In integration x dm/ M here x is COM of dx !!! Don't forget it!!!!!! it's not distance of dm from reference!
    ok that's it!✨😁
