A falling object traveled can be moldeled by equation d= 1/2 at 2 where a is acceleration and t time fallen how do you finf t in terms of a and d ex. T= square 2d/a

Respuesta :

Answer:

[tex]t = \sqrt{\frac{2d}{a}}[/tex]

Step-by-step explanation:

Given

[tex]d = \frac{1}{2}at^2[/tex]

Required

Solve for t

To do this, we simply make t the subject of formula;

This is done as follows:

[tex]d = \frac{1}{2}at^2[/tex]

Multiply both sides by 2

[tex]2 * d = \frac{1}{2}at^2 * 2[/tex]

[tex]2d = at^2[/tex]

Divide both sides by 2

[tex]\frac{2d}{a} = \frac{at^2}{a}[/tex]

[tex]\frac{2d}{a} = t^2[/tex]

Take square root of both sides

[tex]\sqrt{\frac{2d}{a}} = t[/tex]

Reorder

[tex]t = \sqrt{\frac{2d}{a}}[/tex]
