Answer 1

Answer:

Explanation:

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.
