Asmall car (mass = 156.75 kilograms), moving at 115.5 m/s, crashes head on with a 627 kg truck moving at -74.25 m/s in the opposite direction. if the two cars become intertwined and mangled (inelastic), with what velocities does the wreckage move? (include directions)

explain this to i'm trying to understand this topic and i need some : /

The place you get your hair cut has two nearly parallel mirrors 6.00 m apart. as you sit in the chair, your head is 2.00 m from the nearer mirror. looking toward this mirror, you first see your face and then, farther away, the back of your head. (the mirrors need to be slightly nonparallel for you to be able to see the back of your head, but you can treat them as parallel in this problem.) how far away does the back of your head appear to be?
