Question

Resolver el siguiente cuadro

Answer 1

Explicación:

a)

[tex]vf - vo = a \times t[/tex]

[tex]8 - 4 = 2a[/tex]

[tex]a = \frac{4}{2} = 2[/tex]

b)

[tex] {vf}^{2} = {vo}^{2} + 2ax[/tex]

[tex] {12}^{2} = {8}^{2} + 2 \times 2x[/tex]

[tex]144 = 64 + 4x[/tex]

[tex]4x = 80[/tex]

[tex]x = \frac{80}{4} = 20[/tex]

c)

[tex]x = vo \times t + \frac{a \times {t}^{2} }{2} [/tex]

[tex]x = 4 \times 3 + \frac{1 \times {3}^{2} }{2} [/tex]

[tex]x = 12 + \frac{9}{2} = \frac{33}{2} [/tex]

d)

[tex]v = \frac{x}{t} [/tex]

[tex]t = \frac{x}{v} = \frac{4}{12} = \frac{1}{3} [/tex]

e)

[tex]vf - vo = a \times t[/tex]

[tex]vo = \frac{vf}{a \times t} = \frac{10}{3 \times 2} = \frac{10}{6} = \frac{5}{3} [/tex]

f)

[tex] {vf}^{2} = {vo}^{2} + 2ax[/tex]

[tex] {vf}^{2} = {4}^{2} + 2 \times 2 \times 5[/tex]

[tex] {vf}^{2} = 16 + 20[/tex]

[tex]vf = \sqrt{36} = 6[/tex]

g)

[tex]v = \frac{x}{t} [/tex]

[tex]v = \frac{2}{2} = 1[/tex]

h)

[tex]{vf}^{2} = {vo}^{2} - 2ax[/tex]

[tex]0 = 16 - 8a[/tex]

[tex]a = \frac{16}{8} = 2[/tex]
