What Are the Equations for Projectile Motion?

In summary, the problem involves a firefighter standing 50.0 m away from a burning building and spraying water at an angle of 40.0° above the horizontal with a speed of 30.0 m/s. The question is asking for the height at which the water will strike the building. To solve this, we need to use equations for projectile motion.

Homework Statement



A firefighter, 50.0 m away from a burning building, directs a stream of water from a fire hose at an angle of 40.0° above the horizontal, as in figure. If the speed of the stream is 30.0 m/s, at what height will the stream of water strike the building?

The Attempt at a Solution


Im really not sure how to answer the problem. I know that you are supposed to integrate the height into equation. But our teacher didn't appropriately give us the needed materials.

Related to What Are the Equations for Projectile Motion?

1. What is 2D Motion F(h) Calculation?

2D Motion F(h) Calculation is a mathematical method used to calculate the motion of an object in two-dimensional space, taking into account both its horizontal and vertical components.

2. How is 2D Motion F(h) Calculation different from 1D Motion?

In 1D Motion, only the motion along a single axis (either horizontal or vertical) is considered. In 2D Motion, the motion along both axes is considered simultaneously.

3. What is the formula for calculating 2D Motion F(h)?

The formula for 2D Motion F(h) calculation is F(h) = ma, where F(h) is the net force acting on the object, m is the mass of the object, and a is its acceleration in the horizontal direction.

4. What are some real-life applications of 2D Motion F(h) Calculation?

2D Motion F(h) Calculation is used in many fields such as engineering, physics, and sports to analyze and predict the motion of objects in two-dimensional space. It is also used in the design of structures and machines to ensure their stability and safety.

5. What factors can affect the accuracy of 2D Motion F(h) Calculation?

Some factors that can affect the accuracy of 2D Motion F(h) Calculation include air resistance, friction, and external forces acting on the object. It is important to consider these factors and make necessary adjustments to the calculations for more accurate results.
