The distance traveled by a free falling object can be modeled by the equation d = 1 / 2at2nd power, where a is acceleration due to gravity and t is the time the object has fallen. What is t in terms of a and d?

t = √ (2d/a)

Step-by-step explanation:

To solve for a variable, undo the operations done to that variable, in reverse order. Here, t is squared, then multiplied by a/2.

d = (a/2) t^2

Multiply by 2/a.

2d/a = t^2

Take the square root.

t = √ (2d/a)
