Two spheres are launched horizontally from a 1.0m high table. Sphere A has a mass of 1.0kg and is launched with an initial speed of 5.0 m/s. Sphere B has a mass B has a mass of 0.4kg and is launched with an inital speed of 2.5 m/s.
Compare the times for each sphere to hit the floor.
Compare the distances that each travels from the edge of the table.
I just need some explanation in the concept of the first question.
I know the the equation used to find the time is [tex] t = \sqrt{ \frac {2h}{g}} [/tex] and the answer is 0.45s
But I don't understand why the different masses and velocities don't have an effect on the time to fall.
