- What is the kinetic energy ,KE, per unit volume V of blood that has a speed of 0.5 m/s. Take density ofƒâblood = 1.0x103kg/m3
KE=ρv²/2= 1•10³•0.5²/2=125 J
my dear , how did you get this formula of KE, KE=mv2/2 and the mass is equal to (rho)(volume ) so KE=(RHO)(VOLUME)(V2)/2 ,, I confused , can you explain more please
kinetic energy per unit volume V
KE₁ =KE/V= mv²/2V =ρV•v²/2V = ρv²/2
