A city holding tank for water sits 21.0 above the city. If a house near the holding tank was on fire, to what height would firefighters have to drain the tank so water sprayed from the bottom of the tank hits the top of the house at its center, 10.0 m above the ground and 12.0 m away? QUESTION 2 Consider the water tank from the previous question. What is the speed (in m/s) of the water as it leaves the bottom of the tank? QUESTION 3 Assume the tank from the previous questions is sealed airtight with an air gap between the water's surface and the top of the tank. The air pressure in the air gap is 25.0 kPa, while atmospheric pressure outside the tank is 101.4 kPa. Assuming the velocity of the water level in the tank is effectively zero, to what height will firefighters now need to drain the tank so water hits the burning house? (Assume the density of the water is 1000 kg/m3. Report your answer to two decimal places.)
Displacement, Velocity and Acceleration
In classical mechanics, kinematics deals with the motion of a particle. It deals only with the position, velocity, acceleration, and displacement of a particle. It has no concern about the source of motion.
Linear Displacement
The term "displacement" refers to when something shifts away from its original "location," and "linear" refers to a straight line. As a result, “Linear Displacement” can be described as the movement of an object in a straight line along a single axis, for example, from side to side or up and down. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Linear displacement is usually measured in millimeters or inches and may be positive or negative.
