Solution

Step 1: Given Data
Mass (m) $= 15 k g$
Displacement (s) $= 1.5 m$
Acceleration due to gravity (g) $= 10 m s^{- 2}$
Step 2: Calculating force
$F o r c e (F) = M a s s (m) x A c c e l e r a t i o n d u e t o g r a v i t y (g)$
$F = m x g F = 15 x 10 F = 150 N$
Step 3: Calculating work done
$W o r k d o n e (W) = F o r c e (F) x D i s p l a c e m e n t (s)$
$W = F x s W = 150 N x 1.5 m W = 225 J$
Hence, the work done by the porter on the luggage is $225 J$ .
