A 3520 kg truck moving north at 16.0 m/s makes an INELASTIC collision with an 1480 kg car moving 21.0 m/s east. What is the magnitude of their (joint) velocity after the collision?

depends on what you mean by "group." for order, it would be coleoptera (beetles). for class, it would be insecta (insects). for phylum, it would be the arthropoda (animals with jointed exoskeletons).

explanation:

c because the action was the roller coaster reaches bottom of hill (action) reaction would be blood tends to drain away from head

hope this !

i really dont know but i will try okay.

so i think u would just add all them up and get your answer..
