A body is dropped from the top of a tower, 90 m high and at the same time another stone is projected vertically upwards from the bottom. If they meet half way up, what is the initial velocity of the projected body?

Answer:
The same speed (opposite velocity) as the falling object reaches as it arrives halfway..
Because they both lose/gain velocity at the same rate (equal acceleration by gravity) in the same time (from the start of the experiment until they meet halfway)
I’m guessing that’s the main point. The actual value is 29.7 m/s upwards and they meet up after ~3 second
