OMG, TSny. You just made me realize how negligent I am when solving problems. No wonder why I am so conscious about myself and never sure if it's wright or wrong. I'm really grateful to you :) I know on what I have to work on (God, I feel so stupid for not putting a ratio in correctly). Went...

Thank you guys for your help. It’s clear to me now that my solving process is solid, only have to check now for different parameters (cylinder, maybe they made extra typo for initial condition?). I appreciate your help!

The factor 1/2 is correct. I checked my solution process and there is no factor in front of g^2*t^2 so when dividing by 2 we get 1/2.

True, good idea. Didn’t even considered it.

That's right. Then the smallest possible altitude has to come from time t which we can get from w/2.

Thank you for a warm welcome :smile: Even if I subtract 30m, then my result is 365.5m. Still figuring out where did those 60m came from.

A plane is flying 80km/h in horizontal direction and it has to drop a bomb into 30m wide and 30m deep hollow. What is the smallest possible height for the plane to fly above hollow if the bomb successfully hits the bottom? I made a mistake somewhere but not sure where... the correct result is...
