A ball rolls along the top of a 2.8 m high table with a constant velocity. It reaches the edge of the desk and hits the ground 0.35 m from the dusk. What was the initial velocity of the ball as it rolled across the table? Please help asap!

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.
