Nonlinear method for boundary value problems of a constant function.

the question Im having a hard time dealing with is this equation

y"(t)=-g where g is the gravity at 9.8m/s^2

and the boundaries are

y(0)=0.9144 and y(3)=0

how to solve this problem? I am having trouble with runge kutta since it is only a constant function? what to do pls?

I need to know how many shots to and the graph. thanks

Hello, Marcorupert!

From your title, you're making the problem sound trickier than it is.

Thanks But I need to know the first shot of the graph in nonlinear method. :/
