A roller coaster moves 200ft horizontally it rises 135ft at angle of 30degrees above horizontal It travels 135ft at angle of 40degrees below horizontal What is displacement from start point to end?
420 feet at about an angle of -3 degrees.
What is the object in angle of elevation and depression?
It can be any object that is above or below the horizontal from the perspective of a viewer.
What is the angle of declination and how do you use it?
An angle of declination is relevant when an observer is at a higher altitude than the object being observed. It is the angle made by the line of sight with the horizontal. Suppose this is angle x. Then if the altitude of the observer is known to be h, then line-of-sight distance to the object is h*sin(x). The object is h*tan(x) from the point below the observer at the level of the object.Conversely, if the line-of-sight distance from the object to the observer or the horizontal distance to the point directly below the observer is known, it is possible to calculate the height of the observer.
How do you find the angle of depression?
The angle below horizontal that an observer must look to see an object that is lower than the observer. Note: The angle of depression is congruent to the angle of elevation (this assumes the object is close enough to the observer so that the horizontals for the observer and the object are effectively parallel; this would not be the case for an astronaut in orbit around the earth observing an object on the ground).
A ball is thrown with a velocity of 40 meters per second at an angle above the horizontal. If the ball attains its maximum range what was the value of the angle?
At 45 degrees. Yay! I got a proof done, check the link below, back to studying derivations for a infinite line of charge, ewww. The Related Question may answer yours. (See below left.)
