As soon as a ball was allowed to fall from rest from height h, a second ball was thrown upwards from the ground in the vertical direction. For two balls to meet at height h / 2, what should the initial velocity of the second ball be?
Recall the famous experiment of Galileo Galilei on top of the leaning tower of Pisa? If he accidentally dropped one stone 1.0 s ahead of the other, with what initial velocity (in m/s) must the second stone would have to be thrown if the two stones would hit the ground at the same time? Note: The tower is 54 m high.
