Question

A 4.0g slug moves at a speed of 3.0cm/min. Hoe much energy would the slug expend in climbing a plant stalk 16cm high? At what rate would this energy be expended? Finally, if the slug’s muscles are only 18% efficient, how much chemical energy must have been converted in order for the slug to climb the plant?

Answer 1

*How

Answer 2

work = energy = mgh

time = distance/speed
power = work/time

chemical energy = energy/.18
