Homework Statement
two cars collide with each other and basically go different directions
m1 starts out going West and m2 starts out going North
I have set sign conventions to have North + and West -
East + and south -
v1 and v2 are unknown but v1' and v2' are know v1'=19.4 m/s (57 N of W)
v2'=11.4 m/s (44 N of W)
masses are m1= 765 kg and m2=1100 kg i know that Pi=Pf
equation for momentum
m1v1+m2v2=m1v1'+m2v2'
cos law, sine law and tan law may be required due to angles
i must figure out v1 and v2, the initial velocities for the cars
