Alemming running 2.87 meters per second runs off of horizontal cliff and lands in the water 5.32 m away from the base of the cliff how high was the cliff

16.8 m

Explanation:

The motion of the lemming is a projectile motion, consisting of two independent motions:

- on the horizontal (x) axis, a uniform motion, with constant speed v = 2.87 m/s

- on the vertical (y) axis, an accelerated motion, with constant acceleration (downward)

The lemming lands in the water at x = 5.32 m away from the bas of the cliff, so we can calculate the time it takes to hit the water:

And now, by considering the motion on the vertical direction:

we can find the height of the cliff (h) by requiring that y(t)=0:

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).

the answer would be c
