Hey all, I've been lurking for a while to try and see if these problems were solved already but I couldn't find anything so here I am posting!
Question #2:A ball is thrown straight upward from the ground. The ball passes a window 4.35 m above the ground and is seen to descend past that same window 3.68 s after it went by on the way up.
1. What is the total length of time the ball is in the air?
[tex]
v = v_0 + a t
[/tex]
[tex]
x = x_0 + v_0 t + (1/2) a t^2
[/tex]
[tex]
v^2 = v_0^2 + 2 a \Delta x
[/tex]
and Quadratic formula
I tried finding the velocity, max height and then plugging it in the quadratic formula but it is not the right answer. I'm not sure how else to do it? Any help would be greatly appreciated
