Issolvi 1/2mv^2=1/2*(2.1*10^3)(2.9*10^3)^2

$$\frac { 1 } { 2 } m v ^ { 2 } = \frac { 1 } { 2 } \cdot ( 2.1 \times 10 ^ { 3 } ) ( 2.9 \times 10 ^ { 3 } ) ^ { 2 }$$

Solvi għal m

$$m=\frac{17661000000}{v^{2}}$$

$$v\neq 0$$

Passi biex Issolvi l-Ekwazzjoni Lineari

Annulla \frac{1}{2} fuq iż-żewġ naħat.

$$mv^{2}=2.1\times 10^{3}\times \left(2.9\times 10^{3}\right)^{2}$$

Ikkalkula 10 bil-power ta' 3 u tikseb 1000.

$$mv^{2}=2.1\times 1000\times \left(2.9\times 10^{3}\right)^{2}$$

Immultiplika 2.1 u 1000 biex tikseb 2100.

$$mv^{2}=2100\times \left(2.9\times 10^{3}\right)^{2}$$

Ikkalkula 10 bil-power ta' 3 u tikseb 1000.

$$mv^{2}=2100\times \left(2.9\times 1000\right)^{2}$$

Immultiplika 2.9 u 1000 biex tikseb 2900.

$$mv^{2}=2100\times 2900^{2}$$

Ikkalkula 2900 bil-power ta' 2 u tikseb 8410000.

$$mv^{2}=2100\times 8410000$$

Immultiplika 2100 u 8410000 biex tikseb 17661000000.

$$mv^{2}=17661000000$$

L-ekwazzjoni hija f'forma standard.

$$v^{2}m=17661000000$$

Iddividi ż-żewġ naħat b'v^{2}.

$$\frac{v^{2}m}{v^{2}}=\frac{17661000000}{v^{2}}$$

Meta tiddividi b'v^{2} titneħħa l-multiplikazzjoni b'v^{2}.

$$m=\frac{17661000000}{v^{2}}$$

Solvi għal v

$$v=29000\sqrt{\frac{21}{m}}$$

$$v=-29000\sqrt{\frac{21}{m}}\text{, }m>0$$
