If a fisherman applies a horizontal force with magnitude 47.0 NN to the box and produces an acceleration of magnitude 3.20 m/s2m
musickatia [10]

Answer:

The correct solution is "14.6875 kg".

Explanation:

Given values:

Force,

F = 47.0 N

Acceleration,

a = 3.20 m/s²

Now,

⇒ Force=Mass\times Acceleration

or,

⇒       F=ma

⇒    47.0=m\times 3.20

⇒       m=\frac{47.0}{3.20}

⇒           =14.6875 \ kg

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
