With what initial velocity must you throw a ball from a second-story window (h=4.0 m) in order for it to reach the ground in half the time it would have taken if it had been dropped and not thrown? -6.6m/s (this is the answer, how do i get it tho?)

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).
