What is the angle of elevation between two buildings with different heights?

  • Thread starter xxl69
  • Start date
In summary, the conversation is about solving a problem involving an object's height at a given time and finding the angle of elevation for two buildings. The person asking for help is advised to use their knowledge of quadratic formula and trigonometry to solve the problems, and to show their own work.

1.Can anyone help please solve this. h=-6t2(squared)+180t at what time does the object reach 1325 m

2. there are 2 buldings 8m aparts, one is 16 m tall and the other one is 9m tall. find the angle of evelation of each side

You need to show your work. What are you having problem with? These seem like straightforward questions.

Doesn't your textbook provide an example of a similar or related problem? You have two variables in your equation. If you know one of them, how can you determine the other?

The first part is simple maths.Use your quadratic formula knowledge to the maximum.
The next part is simple trigonometry.Use tan theta to feel comfortable. ;p
Show some work.A man without his own work, even though he may be genius, is a superstar without films at hand.
 

1. What does the equation h = -6t2 + 180t represent?

The equation represents the height of an object (h) in meters as a function of time (t) in seconds, assuming that the object is thrown or dropped from a certain height and is affected by gravity.

2. How do you solve the equation h = -6t2 + 180t?

To solve the equation, you can use the quadratic formula or factoring. The resulting solutions will represent the time when the object reaches its maximum height and when it hits the ground.

3. What is the physical significance of the coefficient -6 in the equation?

The coefficient -6 represents the acceleration due to gravity (9.8 m/s2) multiplied by a negative sign, indicating that the object is moving downwards due to the force of gravity.

4. Can this equation be used to solve for the distance traveled by the object?

No, this equation only represents the height of the object as a function of time. To calculate the distance traveled, you would need additional information such as the initial velocity of the object.

5. How can this equation be applied in real-world situations?

This equation can be used to model the motion of objects affected by gravity, such as a ball being thrown or a person jumping. It can also be used in physics and engineering to analyze and predict the trajectory of projectiles.
