A 4.0-m-diameter playground merry-go-round, with a moment of inertia of 300 kg⋅m2 is freely rotating with an angular velocity of 2.5 rad/s .Ryan, whose mass is 60 kg , runs on the ground around the outer edge of the merry-go-round in the opposite direction to its rotation. Still moving, he jumps directly onto the rim of the merry-go-round, bringing it (and himself) to a halt.

How fast was Ryan running when he jumped on?

a.6.3 m/s

b.10 m/s

c.3.1 m/s

d.12 m/s

e.13 m/s

seeing the graph would

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.
