Asked by Laura
Two spheres are launched horizontally from a 1.1 m -high table. Sphere A is launched with an initial speed of 4.5 m/s . Sphere B is launched with an initial speed of 1.5 m/s . What is the distance that sphere A travels from the edge of the table? What is the distance that sphere B travels from the edge of the table?

first, figure how long it takes to fall 1.1 meters.
s = 4.9t^2
Then, using that t, figure how far horizontally the travel, since
s = vt
Naturally, since B's speed is 1/3 of A's, it will travel 1/3 as far, since both balls take the same time to drop to the floor.
