What is a horizontal angle?
A horizontal angle is an angle between lines on a horizontal plane.
What is horizontal as opposed to at an angle?
this is horizontal: ---------------------------- / / this is at an angle: / / /
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.
The angle formed by a horizontal line?
The angle formed by a horizontal line is 180o.
What is the horizontal distance formula?
The answer depends on the context: If you have a distance vector of magnitude V, that is inclined at an angle q to the horizontal, then the horizontal distance is V*cos(q).
Where A Particle Is Projected Along A Linear Plane. The Horizontal Component Of The Velocity Is Twice The Vertical Component What Is The Initial Magnitude Of The Velocity And The Angle At Which It Is?
The initial magnitude of the velocity is sqrt(5) times the horizontal component. This results in a velocity vector that is inclined at an angle of arctan(2) ≈ 63.43 degrees with respect to the horizontal.
How do you plot a trigonometry graph?
You plot the magnitude of the angle along the horizontal axis and the value of the trigonometric ratio on the vertical axis.
What is a horizontal angle?
A horizontal angle is an angle between lines on a horizontal plane.
A man pulls a 50 kilogram box 20 meters across the floor with the aid of a rope tied to the box The rope makes an angle of 30 degrees with the horizontal In pulling the box the man exerts a force of?
The man exerts a force of 245 Newtons to pull the box. This force can be calculated by resolving the force into its horizontal and vertical components. Given that the angle is 30 degrees, the horizontal component of the force can be found using trigonometry.
What is horizontal as opposed to at an angle?
this is horizontal: ---------------------------- / / this is at an angle: / / /
What is the resultant magnitude resultants magnitude and direction if five forces that is 20 kilonewton 15 kilonewton 25 Kille Newton's 30 kilonewton and 10 kilo Newton act from one of the angle point?
To find the resultant magnitude and direction of the five forces acting at an angle, you can resolve each force into its horizontal and vertical components using trigonometry. Then, sum up all the horizontal components and vertical components separately to find the resultant horizontal and vertical components. Finally, use these components to calculate the magnitude and direction of the resultant force using trigonometry.
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.
Will a vector at 45 degrees to he horizontal be larger or smaller than its horizontal and vertical components?
The magnitude of the vector at 45 degrees to the horizontal will be equal to the magnitude of its horizontal and vertical components. This is because the components are obtained by using trigonometric functions of the angle, and in this case, at 45 degrees, those functions yield the same value for both the horizontal and vertical components as the magnitude of the vector.
What angle above the horizontal should a projectile be fired to produce the greatest downrange distance?
its 45 degree
How can a force be resolved in to rectangular components?
A force can be resolved into rectangular components by identifying its horizontal and vertical components. This can be done using trigonometry, specifically sine and cosine functions. The horizontal component is found by multiplying the magnitude of the force by the cosine of the angle it makes with the horizontal axis, and the vertical component is found by multiplying the magnitude of the force by the sine of the angle.
