hi.. I am having difficulty solving 2D momentum-collision questions.. i can do linear ones but somehow i don't know what to do for 2D ones.. can someone please help me?
1. A 3.2-kg hawk soaring at 20 m/s [N] collides with a 0.50-kg sparrow flying at 5.0 m/s [W]. If both the hawk and sparrow are on the same horizontal plane, find their velocity if the hawk hangs on to the sparrow after collision.
2. A 3000-kg car traveling at 20 m/s [N] collides with a 5000-kg truck moving east on an icy road. The bumpers of the two vehicles become entangled and the vehicles remain joined after the collision. Calculate the initial speed of the truck if both vehicles after collision go [E 30 N].
