Firemen are shooting a stream of water at a burning building. A high-pressure hose shoots out the water with a speed of 23.0m/s as it leaves the hose nozzle. Once it leaves the hose, the water moves in projectile motion. The firemen adjust the angle of elevation of the hose until the water takes 3.10s to reach a building 37.0m away. You can ignore air resistance; assume that the end of the hose is at ground level.
Find the angle of elevation of the hose.
Find the speed of the water at the highest point in its trajectory.
Find the acceleration of the water at the highest point in its trajectory.
How high above the ground does the water strike the building?
How fast is it moving just before it hits the building?
Two water reservoirs are open to the atmosphere. The manometer contains mercury with the density of 13,600kg/m cubed. What is the difference in elevation if the manometer reading is 25cm.
A child and sled with the combined mass of 60.4 kg slide down a frictionless hill. If the sled starts from rest and has a speed of 13.4 m/s at the bottom, what is the height of the hill.
