9.8 is superman's velocity. I'm multiplying it by his mass because I want the momentum of Superman. The line is titled x because this is 2d momentum and we need both x and y to get final velocity of x and final velocity of y

Answer I got was 7.37m/s

Then I put it into a momentum equation initial and final, solved for vx and vy and total velocity

Then I found superman's velocity using the time for Louiss to reach down to Superman and the length of the pit

First I found Louiss velocity using this formula in the above image

Hi again. I tried my best to solve it but I'm not getting the right answer. Can you possibly give it a shot yourself? Or just tell me another hint on how to solve it. Thanks

Yes I will try

Hi, I got 16.1 m/s for Lois velocity. How do I find superman's initial velocity?

Oh alright. Thanks

I'll try to figure it out and get back to you thanks

Oh wait, Lois is falling with gravity, so we know acceleration. Now I can figure out time

Actually no, sorry I haven't learned these

Yes how much time was elapsed because there's no mention of time in the problem

Like I need the time to figure out the velocity from the formula d/t
