how long will it take for a motorcycle to come to a stop from 35 m/s if it slows down with an acceleration of -12m/s/s?

It would take 3 seconds approximately.

Explanation:

since it's going to stop it's final velocity is 0m/s

Now,

acceleration = (v-u)/t

or, a = (0-35)/t

or, -12 = -35/t

or, t = -35/-12

so, t = 2.9 seconds.

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:

real, smaller and upside-down.   so the answer should be b.
