Shown on the right is large block 17.0 cm wide, 16.0 cm long, and 27.00 cm high of mass 2.55 kg. This block is passing through air (density ?air = 1.43 kg/m3). Calculate the terminal velocity of the block if it is traveling downward with a drag coefficient ? = 0.882. See the hint panel below for the drag force equation.
