Answer:
78.498N
Explanation:
The Net force provided by the spinnaker can be obtained from Newton's second law of motion as follows;
where m is the mass, v is the final velocity, u is the initial velocity and t is the time interval for which the force acted.
Given;
m =980lb
v = 12mi/h
u =8mi/hr
t = 10s.
It is important to convert all quantities to their SI units where necessary, so we do that as follows;
1lb = 0.45kg,
hence 980lb = 980 x 0.45kg = 441kg.
1mile = 1609.34m
1hour = 3600s,
therefore;
Substituting all values into equation (1), we obtain the following;
<span>Percent composition is the percent by mass of each element present in a compound. In that compound, there are two moles of H atoms and 2 x 1.008 = 2.016 grams. That's how many grams of hydrogen are present in one mole of water. There is also one mole of oxygen atoms weighing 16.00 grams in the mole of water.</span>
Answer:
D is the answer
Explanation: Because I did this
No, because the word might offend that person.

Answer: 9600 J</h2>
The kinetic energy 
of a body is that energy it possesses due to its movement and is defined as:
Where 
is the mass of the body and 
its velocity
.
This has to do with the speed of an object and how much mass it has; basically how the object is moving.
Now, according to this equation and knowing that the mass of the buffalo is 
and its velocity 
:
Therefore the correct option is B.
