[SOLVED] Basic Buoyant Force HW Question
First time doing this, so bare with me:)
A 53kg girl dives off a raft 4m square floating in a freshwater lake. By how much does the raft rise?
Density of water = 1000kg/m^3
Use the equation for buoyant force. Then solve the equation for V.
Of course, volume = L x W x H.
g = 9.8 m/s^2
Fb = weight of girl in Newtons
My teacher gives us the equation for buoyant force as Fb = (density)(volume)(acc.due to gravity).
The answer is to be given in cms (centimeters).
Fb = (1000)(?)(9.8)
I am trying to get the volume, knowing that there is 4m squared. I am just missing the height.
Thanks for any ideas...
