Need help with this physics question. Can't figure it out.

(4%) Problem 19: The left ventricle of a resting adult's heart pumps blood at a flow rate of 83 cm /s, and an average heartbeat increases the pressure in the vessels by 71 mm Hg, the speed of the blood from zero to 35 cm/s, and the height by 10.35 cm. Calculate the total power output of the left ventricle in W. Note that most of the power is used to increase blood pressure, and the density of blood is about 1050 kg/m power =
