How long did it take for the nut to get 2m below?
2=1/2 g t^2 solve for that time.
Now how much more time will it take to get the next 8 meters?
10=1/2g ttotal^2 solve for ttotal, then subtract the t above to find the time for the last 8 meters.
Now, that time is the time it takes the thrown nut to get to the ground.
10=Vo*t+1/2 g t^2 Put that time in the equation, and solve for vo.
