Question

Henry can lift a 200 N load 20 m up a ladder in 40 s. Ricardo can lift twice the load up one-half the distance in the same amount of time.

Which comparison between Ricardo and Henry is correct?

Ricardo exerted a greater force, did the same amount of work, and had the same power output as Henry.
Ricardo exerted a greater force, did the same amount of work, and had a greater power output than Henry.
Ricardo exerted a greater force, did less work, and had a lower power output than Henry.
Ricardo exerted a smaller force, did more work, and had the same power output as Henry.

Answer 1

Ricardo exerted a greater force, did the same amount of work, and had the same power output as Henry.... is correct option...

Hope it helps :)

Answer 2

a) Ricardo exerted a greater force, did the same amount of W, and had the same power output as Henry.

Now if u wanna know the reason the here's the solution.
ATQ
Henry:-
F1=200N
t=40s
s1=20m
so W = F.s
=4000J

Ricardo:-
F2=2(200)
=400N
s2=1/2(s1)
=10m
t=40s
W = 4000J
