In his first measurement, he drops a stone from the edge of a cliff at a certain height in a vertical direction (initial velocity = 0). It takes 4.15 seconds for the stone to fall to the ground. In the second measurement, he throws another stone from the same height with a certain first speed, this time upwards in a vertical direction, the stone rises up to 2 meters from the position where it was thrown and hits the ground 6.3 seconds after it is thrown.
