Make v the subject of the formula in H=m(v²-u²)/2gx

goldfiish [28.3K]

Answer:

$v=\sqrt{\dfrac{H\times 2gx}{m}+u^2}$

Step-by-step explanation:

The given formula is :

$H=\dfrac{m(v^2-u^2)}{2gx}$

We need to find the formula for v.

Cross multiplying the given formula.

$H\times 2gx=m(v^2-u^2)$

Dividing both sides by m. So,

$\dfrac{H\times 2gx}{m}=\dfrac{m(v^2-u^2)}{m}\\\\(v^2-u^2)=\dfrac{H\times 2gx}{m}$

Adding both sides by u².

$(v^2-u^2)+u^2=\dfrac{H\times 2gx}{m}+u^2\\\\v^2=\dfrac{H\times 2gx}{m}+u^2\\\\\text{So},\\\\v=\sqrt{\dfrac{H\times 2gx}{m}+u^2}$

Hence, this is the required formula.

I need help ASAP!!!!!

ycow [4]

Input Data :

Point 1 ( x A , y A ) = (-6, -2)

Point 2 ( x B , y B ) = (1, -6)

Objective :

Find the distance between two given points on a line.

Formula :

Distance between two points = √ ( x B − x A )2 + ( y B − y A ) 2

Solution :

Distance between two points = √ ( 1 - -6 ) 2 + ( − 6 − − 2 ) 2

= √ 7 2 + ( − 4 ) 2

= √ 49 + 16

= √ 65 = 8.0623

Distance between points (-6, -2) and (1, -6) is 8.0623

Or 8.

Best of luck!!
