Question

One of the tallest radio towers is in Fargo, North Dakota. The tower is 629.9 m tall. If a bird lands on top of the tower, so that the gravitational potential energy associated with the bird is 2033.76 J, what is its mass, in kilograms?

Answer 1

Mass × gravitational energy × height
= gravitational potential energy
= joules

by interrelating the formula,

mass (unknown) × 10 × 629.9
= 2033.76

unknown = 0.32??

this is my working ^ but I'm not positive that it's 100% correct!
