1. A 1.60m high water tank, three-fourths full of water, has a drain at bottom inclined 18 degrees above the horizontal and 6.20m from the ground. Determine the range values of the distance from the edge of the tank to the nearest edge of a container 0.65m wide, which will catch the water on the ground. The velocity of water coming out from the drain can be computed using the equation ? = √2?ℎ where ? is the acceleration due to gravity and ℎ is the head (height of water above the drain).
