2. A horse applies a horizontal force of 80 kgf on a cart and
pulls it through a distance of 200 m on a levelled road.
What is the work done by the horse on the cart? What is the
work done by the force of gravity on horse-cart combine?
(Take g = 10 m 2

Answer:
Work done by Horse = 800 * 200 = 160000 J = 160 KJ
Work done by Gravity = 0
Explanation:
Work Done = Force * Displacement
Work done by Horse = 80kgf * 200m
to convert kgf to SI multiply with g
80 kgf = 80 * 10 N = 800 N
Work done by Horse = 800 * 200 = 160000 J = 160 KJ
Work done by Gravity = 0
because no distance is traveled in the direction of gravity so F*D = 0
