tester [92]

Data:
Ep = ? (Joule)
if: F = k.x → F = 10 N
x (displacement) = 0.20 m

Formula:
$Ep = \frac{F*x}{2}$

Solving:
$Ep = \frac{F*x}{2}$
$Ep = \frac{10*0.20}{2}$
$Ep = \frac{2}{2}$
$\boxed{\boxed{Ep = 1\:Joule}}\end{array}}\qquad\quad\checkmark$

Answer:

The ladder is moving at the rate of 0.65 ft/s

Explanation:

A 16-foot ladder is leaning against a building. If the bottom of the ladder is sliding along the pavement directly away from the building at 2 feet/second. We need to find the rate at which the top of the ladder moving down when the foot of the ladder is 5 feet from the wall.

The attached figure shows whole description such that,
