7.5=-16t^2+32t+5.5

Hello anonymous!

 

7.5=-16t²+32t+5.5

 

16t² - 32t + 2 = 0        [ / 16

t² - 2 t + 0,125 = 0                                                  p = -2       q = 0,125

t1;2 = 1 +-√(1² - 0,125)         Quadratic Formula x(1;2) = -p/2 ±√(p²/4 - q)

 

t1 = 1 + 0,935414346693

t1 = 1,935414346693

t2 = 1 - 0,935414346693

t2 = 0,064585653307
