Calculate the magnitude of the acceleration of a sled that is heading down a 42° slope (one that makes an angle of 42° with the horizontal). the coefficient of kinetic friction on ice is μk = 0.100. (take the x direction to be parallel to and down the slope and the y direction to be perpendicular to the slope.)

Explanation:

It is given that,

Angle of inclination of the sled,

The coefficient of kinetic friction on ice is,

Using the free body diagram, the magnitude of the acceleration of a sled that is heading down is given by :

f is the frictional force

So, the magnitude of the acceleration of a sled is . hence, this is the required solution.

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.
