The work done to lift one 25-N box 2 meters is the same as the work done to lift two 25-N boxes??

Question

(one, four, eight) meters ??

Answer 1

one meter; work = force times distance;
25x2=50
50 divided by 50 (25+25) = 1

Answer 2

work = force x distance

in the first case, you are lifting 25Nx 2meters = 50 J

in thesecond case, the amount of force you exert is 50N, and the work done is 50N x distance lifted (which is either 1, 4, or 8 meters).

So for 1 meter, the two boxes require 50J; for 4 meters they require 200J, and for 8 meters they require 400J.

Answer 3

25 N lift
W = Force x distance
W = 50 Nm

50 N lift
W = 50 x 2 Nm
W = 100 Nm

Not the same.

Answer 4
