Answer:

v = 16.58 m/s

Explanation:

Given that,

Mass of a bird, m = 1.6 kg

Kinetic energy of the bird, K = 220 J

We need to find the speed of the bird. The formula for the kinetic energy is given by :

E=\dfrac{1}{2}mv^2

Where

v is the speed of the bird

So,

v=\sqrt{\dfrac{2E}{m}}

Put all the values,

v=\sqrt{\dfrac{2\times 220}{1.6}}\\\\v=16.58\ m/s

So, the speed of the bird is equal to 16.58 m/s.

Answer:

please give me brainlist and follow

Explanation:

Gravitational force keeps it attracted to the Earth, and centripetal force keeps it moving in a circle. ... Explain how Newton's third law and his law of universal gravitation are connected. His third law states that every force has an equal opposite force attracted to it, and that force is caused by gravity.
