Answer:
maximum work is done in the case
D) Clark pushed a crate from the chair, 16 meters across the room, doing 144 J of work.
Explanation:
As we know that the Work done is product of force and displacement
So we have
A) Steve put in 50 J of work moving a box 50 meters.
So here we have
50 = F . 50
F = 1 N
B) Doing 400 J of work, Penny pushed her cat 80 meters.
So here we have
400 = F . 80
F = 5 N
C) Samantha did 365 J of work dragging a wagon across 73 meters of lawn.
So here we have
365 = F . 73
F = 5 N
D) Clark pushed a crate from the chair, 16 meters across the room, doing 144 J of work.
So here we have
144 = F . 16
F = 9 N
So maximum work is done in the case
D) Clark pushed a crate from the chair, 16 meters across the room, doing 144 J of work.
