Hello, I'm studying for a test and this is a question on a practice test...
cos(x)+y^2+(2yx-1)y'=0
I can't separate the variables (it's not homogeneous, either), this isn't exact and bernoulli won't work...
dy/dx=-cos(x)/(2yx-1)-y^2/(2yx-1)
I changed the equation so it would look...
Homework Statement
The escape speed from a very small asteroid is only 28 m/s. If you throw a rock away from the asteroid at a speed of 39 m/s, what will be its final speed?
Vesc= 28m/s
Vi= 39 m/s
Homework Equations
Ks,f + Ke,f + Uf = Ks,i + Ke,i + Ui +W
Vi=sqrt(2GM/r)
