A ball (#1) is rolled, horizontally off a table. The experiment is repeated again, but the ball (#2) is rolled with twice the velocity. What do we know about the times for the two experiments?

They will fell on the ground in the same time as vertical component of velocity or acceleration is same(horizontal component does not affect time of flight). Ball 1 will cover more horizantal disance on the ground due to greater momentum.
