If the truck has a mass of 2,000 kilograms , what's its momentum?(v=35 m/s)

Explanation:

Momentum is the product of mass and velocity.

The mass of the truck is 2,000 kilograms and the velocity is 35 meters per second.

Substitute the values into the formula and multiply.

The truck's momentum is 70,000 kilograms meters per second.

fgravity=10x10=100n case 1

fgravity=30x20=600n case 2

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
