Firemen use a high-pressure hose to shoot a stream of water at a burning building. the water has a speed of 25.0 m/s as it leaves the end of the hose and then exhibits projectile motion. the firemen adjust the angle of elevation î± of the hose until the water takes 3.00 s to reach a building 45.0 m away. ignore air resistance; assume that the end of the hose is at ground level. (a) find î±. (b) find the speed and acceleration of the water at the highest point in its trajectory. (c) how high above the ground does the water strike the building, and how fast is it moving just before it hits the building?

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
