Answer:
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.
