Question

One of the tallest radio towers is in Fargo, North Dakota. The tower is 629m tall, or about 44 percent taller than the Sears Tower in Chicago. if a bird lands on top of the tower, so that the gravitational potential energy associated with the bird is 2033 J, what is the mass?

Answer 1

`\begin{gathered} g=9.81m/s^2 \\ \text{Fargo=h}=629m \\ P=2033\text{ J} \\ m=\text{?} \\ P=\text{mgh} \\ \text{Solving m} \\ m=(P)/(gh) \\ m=\frac{2033\text{ J}}{(9.81m/s^2)(629m)} \\ m=0.33kg \\ \text{The mass of the bird is 0.33}kg \end{gathered}`
