Whakaoti i te {c}{f=-av}{f=10}{v=50}

$$\left. \begin{array} { c } { f = - a v } \\ { f = 10 } \\ { v = 50 } \end{array} \right.$$

Whakaoti mō f, a, v

$$f=10$$

$$a=-\frac{1}{5}=-0.2$$

$$v=50$$

Ngā Upane Otinga

Whakaarohia te whārite tuatahi. Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.

$$10=\left(-a\right)\times 50$$

Whakawehea ngā taha e rua ki te 50.

$$\frac{10}{50}=-a$$

Whakahekea te hautanga \frac{10}{50} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 10.

$$\frac{1}{5}=-a$$

Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.

$$-a=\frac{1}{5}$$

Whakawehea ngā taha e rua ki te -1.

$$a=\frac{\frac{1}{5}}{-1}$$

Tuhia te \frac{\frac{1}{5}}{-1} hei hautanga kotahi.

$$a=\frac{1}{5\left(-1\right)}$$

Whakareatia te 5 ki te -1, ka -5.

$$a=\frac{1}{-5}$$

Ka taea te hautanga \frac{1}{-5} te tuhi anō ko -\frac{1}{5} mā te tango i te tohu tōraro.

$$a=-\frac{1}{5}$$

Kua oti te pūnaha te whakatau.

$$f=10 a=-\frac{1}{5} v=50$$
