Air enters a tank through a pipe with cross-sectional area of 0.2 ft2 with a velocity of 15 ft/s and a density of 0.03 slug/ft3 . Air leaves with a velocity of 5 ft/s and a density equal to that in the tank (which is homogeneously mixed). The initial density of the air in the tank is 0.02 slug/ft3 . The tank volume is 20 ft3 and cross-sectional area of the exit pipe is 0.4 ft2 . Find ��/�� at t = 0

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
