Question

A coolie having 10 kg load on his head covers 100m distance along a platform. Calculate the work done.​

Answer 1

Answer:

500,0

Consider the following,

work done is written as W = F.s = FsCosθ here F is the force applied, s is the displacement caused such that

F = mg = 10 X 10 = 100 N s

W( horizontal direction)= FsCos(0)=500J , θ is the angle between (vectors) F and s now,

as F and s are perpendicular for vertical direction, θ = 90 thus, W = FsCos90 = 0

Answer 2

Explanation:

Work=force×displacement

=weight ×gravity ×displacement

=10×9.8×100

=9800 J
