Answer 1

Respuesta:

Explicación paso a paso:

a )   vf = at + vo

b)   vo = (at^2 - 2d ) / 2t

c)   a =   (vf^2 - vo^2 ) / 2d

d)  t = d / v

Answer 2

Explicación paso a paso:

$a = \frac{vf - vo}{t} \\ at = vf - vo \\ at + vo = vf \\ d = vo.t + \frac{a {t}^{2} }{2} \\ d - \frac{a {t}^{2} }{2} = vo.t \\ \frac{d}{t} - \frac{a {t}^{2} }{2t} = vo \\ \frac{d}{t} - \frac{at}{2} = vo$

${v}^{2} f = {v}^{2} o + 2ad \\ {v}^{2} f - {v}^{2} o = 2ad \\ \frac{ {v}^{2}f - {v}^{2}o }{2d} = a \\ v = \frac{d}{t} \\ t = \frac{d}{v}$
