The power of a machine is 6000 W. This machine is scheduled for design improvements. Engineers have reduced the time for the output by one half from 15 s to 7.5 s. What work would be required to cut the time in half.
Step #1
Step #2
Step #3

Explanation:

Work = power × time

W = (6000 W) (7.5 s)

W = 45,000 J

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:

f is prop to m1xm2 double m1 double force
