. On a horizontal, frictionless surface, a 9.00 kg objectinitially moving east at 4.00 m/s collides with a 3.00 kg objectthat was initially moving north at 10.0 m/s. After the collision,the three-kilogram object moves with a velocity o 12.00 m/sdirected 32.0o north of east. (a) Calculate the velocity of thenine-kilogram object after the collision, and (b) determine bycalculation the type of collision that occurred.
