It's a basic freefall equation: First the total time they are in the air will remain the same because the only acceleration will be gravity. So you can calculate time with 0=(6.8sin(36))t-4.9t^2, as you would for any free fall. The horizontal velocity will tell us how far ...

calculus differential equation
Find in implicit form the general solution of differential equation dy/dx=2(e^x-e^-x)/y^2(e^x+e^-x)^4 with (y>0). I know this requires a seperation of variables but I beyond that I am confused by how.Thanks.
