In this unit, you learned about Athenian democracy and government in ancient Greece. What were some of the main characteristics of Athenian democracy? How is Athenian democracy similar to modern democracy? How is it different? Do you think Athenian democracy would be possible in the United States today? Why or why not? (PLEASE HELP, WORTH 70 POINTS)

under this system all male citizens had equal political rights freedom of speech and the opportunity to participate directly in the political Arena

the velocity you are looking for is made up of two parts: horizontally velocity, vh, and its vertical velocity, vv. the actual velocity of the ball will be these two parts added together, and because velocity is a vector then they will need to be added vectorially.  

neglecting air resistance etc etc.,  

the horizontal velocity component will be constant (because there is no accelerating force in the horizontal direction.  

vh = 8 ms-1  

the vertical velocity component has an accelerating force: 'g'.  

using v = u +at where a = g = 9.81 ms-2.  

the vertical component of velocity, vv = 0 + gt = vv =9.81 x 2  

vv = 19.62 ms-1 . the zero appears because the virtical component of velocity at time t=0 is zero. remember, the ball was thrown horizontally.  

how fast it will be moving (it actual path (being a parabola )) will be the vector sum of these two.  

adding vectorally gives: -  

v = sqr root (8^2 + 19.62^2) = sqr root(64+384.9) = 21.18 or 21.2 ms-1

explanation:

as the height from which the ruler was dropped increased, the speed of the ruler at ryan's hand increased.
