How much work output can a 150hp snowmobile do in 15 seconds if it is 18 % efficiency?
Sav [38]

The work output is 3.02\cdot 10^5 J

Explanation:

The power of the snowmobile is

P=150 hp

Keeping in mind that

1 hp = 746 W

We can convert it into Watts:

P=(150)(746)=111,900 W

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

E=Pt

where

P = 111,900 W is the power used

t = 15 s is the time interval

Substituting,

E=(111,900)(15)=1.68\cdot 10^6 J

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

W=0.18E=(0.18)(1.68\cdot 10^6)=3.02\cdot 10^5 J

Amanda [17]

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.
