LOL , so the rock has a final velocity of
5 mps and it has traveled 19 meters vertically when it
impacted the ground 122.5 meters downwards from
where you threw the rock.


Quote:
m = I threw the rock horizontally at 3ms
u = I didn't quite get it horizontal it was 2ms downwards
a = gravity = 9.8m/s
t = time from throw

So lets do 1 second intervals of t.

t=0sec ... 2D coord = (3*0, 1/2*9.8*0^2) = (0, 0)
t=1sec ... 2D coord = (3*1, 1/2*9.8*1^2) = (3, 4.9)
t=2sec ... 2D coord = (3*2, 1/2*9.8*2^2) = (6, 19.6)
t=3sec ... 2D coord = (3*3, 1/2*9.8*3^2) = (9, 44.1)
t=4sec ... 2D coord = (3*4, 1/2*9.8*4^2) = (12, 78.4)
t=5sec ... 2D coord = (3*5, 1/2*9.8*5^2) = (15, 122.5)


Im beginning to understand a little more about how you
believe things the way you do.

3/4 inch of dust build up on the moon in 4.527 billion years,LOL and QM is fantasy science.
