Me ayudan a despejar
1) MV=Ft despejar t
2) mV2 - mV1=Ft despejar V2
3) Vf=V0+at despejar a
4) C^2=a^2+b^2 despejar b
5) P1V1/T1 = P2V2/T2 despejar T1

Answer 1

Respuesta:

Despejamos las expresiones:

1.

$mv = Ft \\ \\ \frac{mv}{F} = t \\ \\ t = \frac{mv}{F}$

2.

$m {v}_{2} - m{v}_{1} = Ft \\ m {v}_{2} = Ft + m{v}_{1} \\ \\ {v}_{2} = \frac{Ft + m{v}_{1}}{m}$

3.

$v_{f} = v_{0} + at \\ v_{f} - v_{0} = at \\ \\ \frac{v_{f} - v_{0}}{t} = a \\ \\ a = \frac{v_{f} - v_{0}}{t}$

4.

${c}^{2} = {a}^{2} + {b}^{2} \\ {c}^{2} - {a}^{2} = {b}^{2} \\ \\ {b}^{2} = {c}^{2} - {a}^{2} \\ \\ b = \frac{ + }{} \sqrt{ {c}^{2} - {a}^{2} }$

5.

$\frac{p_{1} v_{1}}{T_{1} } = \frac{p_{2} v_{2}}{T_{2} } \\ \\p_{1} v_{1} = \frac{p_{2} v_{2}}{T_{2} }( T_{1}) \\ \\ \frac{p_{1} v_{1}T_{2} }{p_{2} v_{2}} = T_{1} \\ \\ t_{1} = \frac{p_{1} v_{1}T_{2} }{p_{2} v_{2}}$
