Can somebody help me with the graphs to this question:

A snowball rolls off a barn roof that slopes downward at an angle of 40 ∘ (Figure 1) . The edge of the roof is 14.0 m above the ground, and the snowball has a speed of 7.00 m/s as it rolls off the roof. Ignore air resistance.

I'm using the equations y=V_y*t+(1/2)*g*t^2
x=V_x*t
V_y=7*sin(40)
and V_x=7cos(40)

I managed to get the V_x(t) graph right as the constant of 7*cos(40), but every other way I try do the y(t) x(t) and V_y(t) it's coming out wrong.
