The work output is 
Explanation:
The power of the snowmobile is

Keeping in mind that

We can convert it into Watts:

The energy used by the snowmobile can be found as follows:

where
P = 111,900 W is the power used
t = 15 s is the time interval
Substituting,

However, the snowmobile is 18% efficient: this means that only 18% of this energy is converted into useful work. Therefore, the work output is

Answer:
5.1 kg
Explanation:
Its mass on the moon is 5.1 kg because mass is an intrinsic property of a material and does not change with location. Although, its weight might vary because its acceleration of gravity g is dependent on the mass M and radius r of the planet(in this case, moon) involved g = GM/r². Since weight W = mg is dependent o g, weight varies but mass remains constant.
