Question

There is an elephant shaped weather vane at the top of a corn dryer tower that is 45 m high. If the weather vane weighs 190 N, what is the Potential Energy that the weather vane has?Potential Energy = Weight x HeightWeight = Potential Energy / HeightHeight = Potential Energy / WeightWeight = Mass x 10Mass = Weight / 10

Answer 1

Given,

The weight, W = 190 N

The height, H = 45 m

The potential energy is calculated by the formula,

$PE=\text{Weight}\times Height$

Calculate the potential energy by substituting the given values.

$\begin{gathered} PE=190\text{ N}\times45\text{ m} \\ PE=8,550\text{ J} \end{gathered}$

Thus, the potential energy is 8,550 Joules.
