Known Variables:
Δy = 1.5 m
v0 = 30m/s at 60° above the horizontal.
t = 4.0 s
a. vfy = v0y + at
0 = 30sin(60) + (-9.8)t
-25.98 = -9.8t
t = 2.65.
4-2.65 = 1.35s.
Δy = v0yt + at^2/2
Δy = 25.98(2.65) + (-9.8)(2.65)^2/2
Δy = 34.44 m
1.5 + 34.44 = 35.94 m.
Δy = v0t + at^2/2
Δy = (-9.8)(1.35)^2/2
Δy = -8.93.
35.94 - 8.93 = 27.01 m.
b. vfy = v0y + at
0 = 30sin(60) + (-9.8)t
-25.98 = -9.8t
t = 2.65.
Δy = v0yt + at^2/2
Δy = 25.98(2.65) + (-9.8)(2.65)^2/2
Δy = 34.44 m
1.5 + 34.44 = 35.94 m.
vfy = v0y + at
vfy = (-9.8)(1.35)
vfy = -13.23 m/s.
I might have gone wrong somewhere so please check my answer! Cheers!
The correct answer to this open question is the following.
It is correct to say that in the period 1of 750-1900 CE, new political ideologies emerged as the world became more modern, industrial, and enlightened.
The Enlightenment impacted the development and course of revolution(s) around the world in that many brilliant thinkers and philosophers of the Enlightenment came up with novel ideas about new forms of government, citizens' rights, social contract, equality, liberty, and private property.
Philosophers like John Locke, Thomas Hobbes, Voltaire, Jean-Jaques Rosseau, and Baron de Montesquiou, were some of the brilliant men than influenced the founding fathers of the United States and the Revolutionary War, as well as the French Revolution or the Independence of México.
For instance, many ideas of the Enlightenment influenced the founding documents of the US such as the Declaration of Independence. For instance, the people's right to be free by its own nature. People born free and their liberty is sacred. Another Enlightenment idea is the power of people to be governed by the right kind of people and citizens can decide to remove them. And of course, the responsibility of the government to protect its citizens.
