When a plane takes off it travels for a horizontal distance of 1400 ft before reaching its maximum altitude of 50000 ft what is the planes angle of elevation as it rises?
When a plane takes off it travels for a horizontal distance of 1400 ft before reaching its maximum altitude of 50000 ft; the plane's angle of elevation as it rises would be 86 degrees.
How do you use a theodolite?
Process of Measuring Horizontal Angles Using a Theodolite 1. Setting up the Theodolite: This includes mounting the theodolite on a tripod and making sure it is comfortable for the user. 2. Unlock the upper horizontal clamp. 3. Rotate the theodolite until the arrow in the upper or lower rough sight points to the feature of interest and lock the clamp. 4. Look through the main eyepiece and use the upper horizontal adjuster to align the vertical lines on the feature of interest. 5. The reading is taken by looking through the small eyepiece. Using the minutes and seconds adjuster set the one of the degrees on the horizontal scale so the single vertical line on the bottom scale is between the double vertical lines under the selected degree. 6. The reading is the degree which has been aligned and the minutes and seconds read from the right hand scale and is the horizontal angle from the reference line. Process of Measuring Vertical Angles Using a Theodolite Process of Measuring Vertical Angles 1. Setting up the Theodolite: This includes mounting the theodolite on a tripod and making sure it is comfortable for the user. 2. Unlock the vertical clamp and tilt the eyepiece until the point of interest is aligned on the horizontal lines. Lock the clamp in place. 3. Looking through the small eyepiece, use the minutes and seconds adjuster to align one of the degrees on the vertical scale with the double lines just below it. 4. The reading is the degree that has been aligned and the minutes and seconds is read from the right hand scale. 5. To complete the reading, it may be necessary to measure the distance from the theodolite to the point of interest. The above is al true, but doesn't discuss the practical uses of a theodolite. For example, if you want to know the height of the top of the gable on a house, you could use a theodolite. First, set up the theodolite (btw, I made one with a piece of copper tube, a protractor and a cheap wooden tripod) as noted above, make sure the ground is pretty level between the house and the theodolite, and then measure the distance from the vertical side of the house to the theodolite. (You may choose to move the theodolite so that the distance is the square of a whole number.) Then aim the scope (tube) at the upper-most point of the gable and note the degree of angle on the protractor. If you have pretty level ground between the theodolite and the house, the angle at the intersection of the side of the house and the ground should be 90 degrees. So, now we have two angles (the 90 degrees at the intersection of the side of the house and the ground, and whatever angle you recorded at the theodolite) and a side (the distance from the house to the theodolite). With this information, you can calculate the third angle and the other two sides, one of which will be the hypotenuse and the other will be -- tada! -- the final leg, which will tell you the height of the point you picked out at the top of the gable.
What are two kinds of measurement in trigonometry?
distance and angle
If you keep th velocity of projection and change the angle of projection from 75 degrees to 45 degrees what will happen to the horizontal distance the projectile travels?
If you keep th velocity of projection and change the angle of projection from 75 degrees to 45 degrees what will happen to the horizontal distance the projectile travels? if you finish the nova net lesson you might learn the answer! It will travel a greater distance!
What is the factor influence the distance and time in projectile motion?
projection speed projection angle projection height
Which information is needed to determine the horizontal distance a projectile travels?
-- the initial horizontal speed of the projectile -- the time it remains in flight before it hits the ground
At what angle from a horizontal should a weapon be fired to achieve minimum distance traveled by the projectile?
Do you really mean minimum distance? This would be achieved if the projectile went straight up and down, ie 90 deg from horizontal. Maximum distance would be obtained at 45 deg to horizontal.
What is the word for the horizontal distance a projectile travels?
range
What do you need to know to be able to determine how far a projectile travels horizontally?
The horizontal velocity of the projectile (and the air resistance if known) will determine the horizontal distance traveled and the time required.
What is Trajectory?
A trajectory is the angle made with the horizontal when a projectile is fired. Suppose the projectile is a cannon ball. Assuming air is frictionless, that cannon ball will travel the greatest distance if the trajectory is 45 degrees from horizontal.
What angle above the horizontal should a projectile be fired to produce the greatest downrange distance?
its 45 degree
What angle a projectile thrown to achieve maximum horizontal distance traveled?
A trajectory of 45 degrees elevation gives the longest horizontal travel- (not taking air drag into consideration nor any aerodynamic properties of a projectile.
What is the horizontal displacement of a projectile?
it depends on the gravitational force of attraction of earth and air resistance. if we are neglecting air resistance, the max.horizontal distance is according to this formulae, V0/2 * sin (2theta) where V0 is the initial velocity theta is the angle with x axis and the projection.
What angle for firing projectiles gives longest time?
45 degrees to the horizontal will give the maximum flight time for a projectile. If a projectile was fired at 90 degrees to the horizontal, (straight upwards) the projectile will go straight upwards (ignoring the shape, form and aerodynamic properties of the projectile). Likewise if you were to fire a projectile at 0 degrees to the horizontal, the projectile would follow said course, IF gravity was not in effect; a projectile needs some form of vertical velocity to overcome gravity. Hence why 45 degrees will give you the longest distance and consequently flight time.
What does horizontal line represent on graph of distance vs time?
constant speed
