Firefighters are throwing a jet of water at a burning building, using a high pressure hose that gives the water a speed of 25.0 m/s when exiting the nozzle. Once it leaves the hose, the water moves with projectile motion. Firefighters adjust the elevation angle of the hose until it takes 3.00 s for the water to reach a building 45.0 m away away. Ignore air resistance and assume that the hose nozzle It is at ground level. 1) Investigate and explain the following concepts: vector, scalar, velocity, speed, distance, displacement and reference system. 2) Solve the following numerically, completely and in detail: a) Calculate the angle of elevation. b) Determine the speed and acceleration of the water at the highest point of its trajectory. c) Determine the height above the ground at which the water hits the building. and with what speed value it does it. 2 3) Analyze and explain how it would affect the previous results if the angle of inclination is increased. 4) Analyze and explain how it would affect the previous results if the angle of inclination is decreased. 5) Analyze and explain how it would affect the previous results if the magnitude of the exit velocity through the nozzle will increase. 6) Analyze and explain how it would affect the previous results if the magnitude of the exit velocity through the nozzle will decrease. 7) Analyze and explain how it would affect the previous results if the wind were a variable to consider. 8) If the water jet reached its maximum height before colliding with the wall of the building, what value should the magnitude of the acceleration have? horizontal and vertical at that moment. 9) If the water jet reached its maximum height before colliding with the wall of the building, what value should the horizontal and vertical speed have in that moment.

4.8**Scalar**: A scalar is a quantity that has only magnitude and no direction. Scalars are represented by a single numerical value without any direction associated with it.
**Velocity**: Velocity is a vector quantity that describes the rate at which an object changes its position. It is the rate of change of displacement with respect to time. The formula for velocity is given by:
**Speed**: Speed is a scalar quantity that describes how fast an object is moving. It is the rate of change of distance with respect to time. The formula for speed is given by:
**Distance**: Distance is a scalar quantity that refers to the total path length traveled by an object. It is always positive and never decreases.
**Displacement**: Displacement is a vector quantity that refers to the change in position of an object. It is the shortest distance between the initial and final position of the object, along with the direction.
**Reference System**: A reference system is a set of axes used to locate the position of objects in space. It provides a frame of reference against which the position, motion, and properties of objects can be measured and described. It typically consists of coordinate axes (x, y, z) and origin points.
**Answer**: The concepts of vector, scalar, velocity, speed, distance, displacement, and reference system provide essential tools for describing motion and position in physics.
