can any one understand my problem?
Hi Guys, I have question on momentum.
A 2000 kg automobile going east on chestnut street at 60mi/hr collides with a 4000kg truck which is going south across chestnut street at 20mi/hr.If they become coupled
on collision, what is the magnitude and direction of their velocity immediately after colliding?
In this case we want to use conservation of linear Momentum.But i have a struggle on their velocity because it is a vector equation, So how can i find their velocity in proper way.
