Find the horizontal velocity component and vertical velocity component, given distance travelled = 1.6 meters, time of flight = 0.12seconds and launch height = 0.05meters

Awater-filled u-tube manometer is used to measure the pressure inside a tank that contains air. the water level in the u-tube on the side that connects to the tank is 5 ft above the base of the tank. the water level in the other side of the u-tube (which is open to the atmosphere) is 2 ft above the base. determine the pressure within the tank.
