1. ### Help with math!?

...tan(y) / (1 + 3 tan^2(y)) = 2 tan(y) / (1 + tan^2(y) + 2 tan^2(y)) = 2 tan(y) / ( sec ^2(y) + 2 tan^2(y)) This is the part where you want to break everything...

3. ### Math help. Suppose that an object is thrown upward..?

h(t) = -16t² + 96t so, h(t) = -16t(t - 6) h(2) will be the height at t = 2 seconds so, h(2) = -16(2)² + 96(2) => -64 + 192 = 128 feet or, h(2) = -16(2)(2 - 6) => -16(2)(-4) = 128 feet :)>

8. ### Physics angular acceleration question?

time t = ω / α = 7.0 rad/ sec / 1.9 rad/ sec ^2 = 3.68 sec   (3.7) n = α /2*t^2/2PI = 0.95*3.68^2/6.2832 = 2.05 revs (2.1)

9. ### Physics angular acceleration question? ?

2Θ = ω *t 2*13.5*6.2832 = 7.20*t  time t = 2*13.5*6.2832 / 7.20 = 23.6 sec   angular acceleration α = (0-ω )/t = -7.2/23.6 = -0.306 rad/ sec ^2
