Question

I am unsure how to solve problems H through L and it's due by Friday!!! pls help! (solve for variable listed on paper from equation)

Answer 1

Explanation:

(h)

`KE= (1)/(2)mv^(2) \\KE=(mv^(2) )/(2) \\2KE=mv^(2)\\2KEm=v^(2) \\v=√(2KEm)`

(g)

`s=((u+v)t)/(2) \\2s=(u+v)t\\(2s)/(t)=u+v\\u= (2s)/(t)-v`

(i)

`s=ut+(1)/(2) at^(2) \\s-ut=(at^(2) )/(2) \\2s-2ut=at^(2) \\√(2s-2ut)=at\\a=√(2s-2ut)-t`

(j)

`(pV)/(T) =nR\\T=(pV)/(nR)`

(k)

`a^(2) -b^(2) +c^(2) \\a^(2) +c^(2) =b^(2) \\b=\sqrt{a^(2) +c^(2) }`

(i)sinθ
`=(a)/(b)`

θ=
`(a)/(sin(b))`
