Math expression, I need to use maths and science help. Math expression does not accept negative numbers.

Just gravity is? I mean it is taking other values if you want instead of 1000UUs/s initial speed maybe 5000 UUs/s…

example:

Vo= 1000 UU/s
g = 980 UU/s
h = 10 UU
D = 2500 UU
angle = ? that is what we are suposed to find that is the formula
t = ? same here we should find that WIP
