2. the 10kg crate as shown in figure 6-51 has an initial velocity of 2 m/s on the inclined plane,
which the coefficient of kinetic friction is 0.3. if a 100n towing force has been applied to the
crate for 8 seconds, calculate the final velocity and the distance of the crate travels during this
time.
u= 2 m/s
f = 100 n

nah.   i'm just sleepy.

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.
