1) a 20 grams mass is moving in a direction with velocity vectors v1=( 10, 3) m/s while a 4.0 grams mass is moving in a direction with velocity vector v2=(20, -14) m/s (just before the collision). They collide head on and stick together.
a)find their velocity vector components after the collison.
b)draw the velocity vectors before the collison, v1, and v2 and after the collision, v
c) draw the momentum vectors, p1, p2, and p, before and after the collison?
