Two objects with same mass. One is being thrown upwards, and the other one is dropped. Do they have the same speed when hitting ground? I think they have. Let's say the object being thrown upwards goes up 3 meters, then starts accelerating downwards. That will be the same as having dropped the object from 3 meters higher. So one object falls for 3 meters longer than the other. Then it must have more time to accelerate, and so it will have a greater velocity when reaching the ground. Why is this not correct?
