Explanation:
Momentum of the system is a constant when there aren't external forces..
So,When first Balls velocity is went down to zero... its momentum is also zero and beacause momentum should be a constant...now second ball must have a momentum of 20 kg * m/s
The radius of Earth's circular trajectory is

The time for the Earth to travel around the Sun is

Thus the velocity is velocity

From this we can deduce the centripetal acceleration

Angular velocity is
Acceleration equals 24 km/s
Average equals 396km/s
The basic relationship between frequency of an electromagnetic wave and wavelength of the wave is

where

is the speed of light.
Manipulating the equation, we can rewrite it as

The frequency of the wave in our problem is

so if we use the previous formula, we find the correspondant wavelength:
