The spring has a constant of 12 N/m and the frictional surface is 0.2 m long with a coefficient of friction µ = 1.78 . The 5 kg block depresses the spring by 15 cm, then is released. The first drop is 2.8 m and the second is 2 m. The acceleration of gravity is 9.8 m/s 2 . µ h L h m k x 1 2 s How far from the bottom of the cliff does it land? Answer in units of m.

cancer risk hope this

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.
