  1. Wait patiently for a helper to come along.
  2. Once someone helps you, say thank you and close the thread with:
+close
  1. Feel free to nominate the person for helper of the week in #helper-nominations
  2. Do not ping the mods, unless someone is breaking the rules.
  3. If you're happy with the help you got here, and the server overall, you can contribute financially as well:

im lost in this

#

any help will be apprecited :c

last fog
#

could u do an integral from up to down in circular slices?

#

and then get the potential energy of each slice and do dh

#

the radius as a function of h would be sqrt(25 - h^2)

#

actually

#

sqrt(25 - (5-h)^2)

#

and potential energy is mgh

#

m is volume * density

#

and we can do the integral for volume

#

int(0 to 5 of (h * sqrt(25 - (5-h)^2)) dh) * density * g

#

the inside of integral is mh

#

and outside is the g

#

i get 5.65 kJ

#

o mf 9.8 not 10

#

i get 5.54 kJ
