Water stands at depth 'd' behind a dam of width 'w'.
i.
Find an expression for the net force of the water on the dam.
ii.
Evaluate the net force on a 100m high dam with a 60m water depth.
Attempt
For the first part:
p=F/A
A=wd
pwd=F
Then integrate from 0 to d which gives .5pw(d^2).
Does this even look remotely correct, i have a feeling there should be a g somewhere in there?
As for the 2nd part I'm stumped, how do I find the p term from that information.
Any help as always is greatly appreciated :)
