A 82.5 kg 82.5 kg horizontal circular platform rotates freely with no friction about its center at an initial angular velocity of 1.71 rad/s1.71 rad/s . A monkey drops a 8.95 kg8.95 kg bunch of bananas vertically onto the platform. They hit the platform at 4545 of its radius from the center, adhere to it there, and continue to rotate with it. Then the monkey, with a mass of 20.9 kg 20.9 kg , drops vertically to the edge of the platform, grasps it, and continues to rotate with the platform. Find the angular velocity of the platform with its load. Model the platform as a disk of radius 1.63 m1.63 m .

f is prop to m1xm2 double m1 double force

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.

54 degrees incident angle = reflected angle

angle is from normal turned to line of ray
