Hi,
could you please help me with following:
----------
two boats traveling in opposite direction with speed v1 and v2
when they are passing by they interchange a parcel of same mass M=50kg
as a result second boat stops and first boat continue traveling in same direction with speed u1=8.5m/s
calculate v1 and v2 when you know masses (including M) m1=1000kg and m2=500kg
------------
I wrote
m1*v1+m2*v2=m1*u1
but I am not able to find out second equation. I tried kinetic energy but
I think it is not conserved.
Thank you
Michael
