Sorry my fault.. It's fμ = m v2/r I forgot to mention the mass. :-p Newton's law is F = ma after all, and the acceleration in this one is the centripetal acceleration that keeps the block moving in circles a = v^2/rNow that you know the friction, you should be able to calculate the...

Although the wooden disk is rotating, the block's motion is circular, that means there must be a force (centripetal force) that keeps it going in circles. In this particular example, it's the friction. Fμ = v2 / R

3/4=0.75 is not the Precentage dude, it's 75%

(Density of the object / density of the fluid) x 100 = Prencentage of object's volume in the fluid

But if the object isn't moving should'nt it mean ƩF = 0 → buoyancy = mg ?? Why should we subtract them?

so dreamy.. no homo

I don't know really. Haven't had any fun in a long, long time. All i do is study nowadays, hopefully it pays off in march I do like watching soccer/football in weekends tho
