Q. A hand-pumped water gun is held level at a height of 0.66m above the ground and fired. The water stream from the gun hits the ground a horizontal distance of 6.60m from the muzzle. Find out the gauge pressure of the water gun's reservoir at the instant when the gun is fired. Suppose that the speed of the water in the reservoir is zero, and that the water flow is steady. Overlook both air resistance and the height difference between the reservoir and the muzzle.
