Identify the variables given and implied in the scenario above.

Pick the other option. d(x) and d(y) are both given in the diagram. d(y) would just be negative since the ball is falling in the downward direction. The only force present is gravity so the only acceleration occurs vertically. The ball is launched horizontally, so there is no initial vertical velocity, but there is an unknown horizontal velocity.
What equation is necessary to solve for how long it takes the marble to land?

e=mc^2
d(x)=v(x)t
F=ma
d(y)=(1/2)gt^2
