I suppose <em>K</em> is the matrix

To compute det(<em>K</em>), you can use a simple cofactor expansion along the first row:

<span>In this expression, the variable ’t’ stands in for any possible value of seconds. Therefore, since you know how long it takes the object to fall in seconds, you can put this into the expression. 16 x (4^2) = 256. The distance is 256ft.</span>
