m = 15kg
g = 10m/s^2
h = 1.5m
As work done by an object is equal to the potential energy stored in an object.
Therefore,
W = mgh
= 15×10×1.5
= 225J.

The formula for work, as we know, is Work = Mass x Gravity x Height.
Here, the mass of the luggage is 15 kg, the constant of gravity is 10 m/s^2, and the height is 1.5 m.
Therefore, the total amount of work done can be calculated by multiplying these three values, that is, Work= 15 x 10 x 1.5 = 225 Joules.
