Question

U0 = 8м/с
g = 1,6м/с в квадрате
Найти S​

Answer 1

Ответ:

$h = \sqrt{ \frac{v {}^{2} }{2g} }$

$a = \frac{v}{t} = \frac{8}{25} = 0.32$

$h = \sqrt{ \frac{8 {}^{2} }{2 \times 1.6} } = 20$

$t = \sqrt{ \frac{2h}{g} } = \sqrt{ \frac{2 \times 20}{1.6} } = 25$

$s = vt + \frac{at {}^{2} }{2}$

$s = 8 \times 25 + \frac{(0.32 \times 25) {}^{2} }{2}$

$s = 200 + 32 = 232$
