If you submerge a 3cm cube of ice in cup of water, with what force will the ice float up to the surface
ρgV, F=ma, ρgh
The Attempt at a Solution
I thought to draw free body diagram of vertical forces with mg of ice cube and ρicegAhtop surface as negative forces and positive buoyant force of ρwaterg(htop surface+.03cm)A summing to Fnet.
End up getting ρwatergV-ρicegV=F
I just want to make sure I got the right densities in right places, in other words when do you use the density of water and when do you use the density of ice?
