A bird flying horizontally accidentally drops a rock it was carrying. 2. 10 s later, the rock's velocity is 22.2 m/s in a -68.2 degrees direction. What was the bird's (and rock's) initial velocity? (Unit = m/s) (Hint: the rock was originally moving with the bird.)

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.
