Sati [7]

Answer:

The value of k is 240

Step-by-step explanation:

$\frac{1}{3}k + 80 = \frac{1}{2}k + 120$

Or, 120 - 80 = $\frac{k}{2} - \frac{k}{3}$

Or, 40 = $\frac{k}{6}$

The equation gives the speed at impact, V metres per second, of an object dropped from a height of h metres. SHOW WORK From what

devlian [24]

Answer:

h = 17.65 m

Step-by-step explanation:

The given equation gives the speed at impact :

$v=\sqrt{2gh}$

h is height form where the object is dropped

Put v = 18.6 m/s in the above equation.

$h=\dfrac{v^2}{2g}\\\\h=\dfrac{(18.6)^2}{2\times 9.8}\\\\h=17.65\ m$

So, the object must be dropped from a height of 17.65 m.
