Explanation:
Why are students in Hawaii required to learn the history of debate surrounding the writing of the first 10 amendments to the constitution? They were not a member of the United States at the time?
The reason they have to learn anything they can about the constitution is because they are governed by it (just as you are).
The reason you have to learn about the Earth's Systems is because currently there is a huge debate about global warming. The problem is that we are not sure what the solution might be and we've already spent billions on reducing our effect on the environment. Billions means your tax dollars (many) or that of your parents. Many scientists are not sure we should be doing anything.
You will enter the work force one day and if you get a good job, you will be taxed. You should never be unaware of what your tax dollars are spent on.
Answer:

Explanation:
m = Mass of bungee jumper = 55 kg
g = Acceleration due to gravity = 
h = Height at the bottom = 40 m
k = Spring constant
x = Displacement of bungee cord = 25 m
Applying the principle of conservation of energy to the system we have

The spring constant of the bungee cord is
.
Velocity of plane is given as
towards north
towards south east
we can write the two velocity in vector form


now the net velocity will be given as



so the resultant velocity will be given as


and the angle of velocity will be


The type of potential energy is elastic energy
At 100 km/hr, the car's kinetic energy is
KE = (1/2) (mass) (speed)²
KE = (1/2) (1575 kg) ( [100 km/hr] x [1000 m/km] x [1 hr/3600 sec] )²
KE = (787.5 kg) (27.78 m/s)²
KE = 607,639 Joules
In order to deliver this energy in 2.9 seconds, the engine must supply
(607,639 J / 2.9 sec) = 209,531 watts
<em>Power = 281 HP</em>
