by flame thrower do you mean Byzantine or "Greek" fire?

angular momentum initial = I omega I = (1/2) m r^2 = (1/2)(50).26^2 860 what? rpm? 860 rev/min * 1/60 min/sec * 2 pi radians/rev = 90 rad/sec so Iw= 152 torque * time = change of angular momentum 250 N * mu * 7.4 sec = 152 I am just guessing at your units for everything

Your answers above seem more oriented to telling us why the empire failed.

I liked your earlier answers better except for the first as Ms Sue pointed out. I might have said something like with the fall of the central government the resulting smaller governments tended not to work together and even attacked each other. the only unifying agency left wa...

left distance = (1/2)1.11 t^2 right distance = (1/2)1.17 t^2 right + left = 36 so 1.11 t^2 + 1.17 t^2 = 72 solve for t then left distance = .5 (1.11 t^2

the smallest of those numbers is(2) (3) 135 has one bigger and one smaller so it is the median the biggest is (1)

initial speed up Vi = 1000 sin 45 = 707 m/s v = Vi - 9.81 t when v = 0, we go no higher t = 707/9.81 = 72 seconds upward h = Vi t - (1/2) 9.81 t^2 h = 707 (72) - 4.9 * 5184 = 50904-25427 25,000 m u = horizontal speed = 1000cos 45 = 707 u t = 707 * 2*72 = 102,000 m

m^2 - 8 m + k (m-x)(m-x) = m^2 -2 x m + x^2 so 2 x = -8 x = -4 x^2 = 16 = k so m^2 - 8 m + 16 in general to complete the square 1 x^2 + b x + c if that is to be a perfect square c = (b/2)^2
