Question

1.one of the tallest radio towers in Fargo, north Dakota. the tower is 629 m 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 birds mass?

Answer 1

The mass of the bird will be 323 grams

Explanation :

Given,

height of the tower, h = 629 m

acceleration due to gravity, g = 10 m/s²

gravitational potential energy, P = 2033 J

let the mass of the bird = m

we know that gravitational potential energy is given by,

P = mgh

=> 2033 = m x 10 x 629

=> m = 2033/6290

=> m = 0.323 kg = 323 grams

Hence the mass of the bird will be 323 grams

Answer 2

Answer:

0.3298 kg or 329.800 in g

Explanation:

We have 2,033 kg m^2/s^2

And 629 m for height

The gravity is 9.8 m/s^2

In finding the mass we have to apply the formula m=GPE/(g)(h)

Solution: m= 2,033 kg m^2/s^2 ÷ (9.8 m/s^2) (629 m)

m=2, 033kg m^2/s^2 ÷ 6, 164.2 m^2/s^2

m= 0.3298 kg or 329. 8 g
