Answer:
Step-by-step explanation:
v=√u*u- 2qs
- [tex]\sqrt{20}[/tex] x 20 - 2q40 = 8
- [tex]2\sqrt{5}[/tex] x 20 - 2q40 = 8
- 40[tex]\sqrt{5}[/tex] - 2q40 = 8
- - 2q40 = 8 - 40[tex]\sqrt{5}[/tex]
- -80q = 8 - 40[tex]\sqrt{5}[/tex]
- q = (8-40[tex]\sqrt{5}[/tex] ) / -80 = [tex]\frac{-1 + 5\sqrt{5} }{10}[/tex] = 1.018
