Let us first know the given: Tennis ball has a mass of 0.003 kg, Soccer ball has a mass of 0.43 kg. Having the same velocity at 16 m/s. First the equation for momentum is P=MV P=Momentum M=Mass V=Velocity. Now let us have the solution for the momentum of tennis ball. Pt=0.003 x 16 m/s= ( kg-m/s ) I use the subscript "t" for tennis. Momentum of Soccer ball Ps= 0.43 x 13m/s = ( km-m/s). If we going to compare the momentum of both balls, the heavier object will surely have a greater momentum because it has a larger mass, unless otherwise the tennis ball with a lesser mass will have a greater velocity to be equal or greater than the momentum of a soccer ball.

Answer:
The manner in which the Earth's movement affect how the Sun is seen is;
The Sun is stationary, but Earth's rotation makes it appear to move East to West across the sky
Explanation:
The Earth's movement affect the way the Sun is seen
The Sun appears to rise in the Eastern part of the sky and continues in motion till the it sets at the Western part of the sky
However, the Sun does not actually move relative to the Earth as seen in the sky. The observed motion of the Sun is due to the counterclockwise rotation of the Earth about its axis
Therefore, the Earth's movement affect the way the Sun is seen by making the Sun appear to move across the sky from East to West
We would need to know the geometry of the system. The formula for the moment of inertia about the axis the axis perpendicular to the plane for common geometries are
Solid cylinder: I = (1/2) MR^2
Hollow cylinder: I = MR^2
Solid Sphere: I = (1/12) ML^2
Square Plate: I = (2/3) MR^2 (where R is half the length of the diagonal)
