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 velocity is sqrt(5) times the vertical component, and its angle relative to the horizontal direction, is 0.46 radians (26.6 degrees).
Why does the horizontal component of velocity for a projectile remain constant while the vertical component changes?
Since the velocity is constant due to the fact that there are no external forces acting in the horizontal direction, if you neglect air resistance, therefore, the horizontal velocity of a projectile is constant.
Is it true that frictional force on a sliding body on a plane is always directed at the angle of friction to the normal?
The frictional force on a sliding body on a plane will be acting parallel to the plane against the motion of the body. But the magnitude of the (kinetic) friction force is proportional to the weight component normal to the plane. The weight component parallel to the plane is the force that tends to slide the body down the inclined plane. When the sliding body has acquire steady velocity, the friction force is equal to the body's sliding force.
An aeroplane flying at a constant velocity releases a bomb. As the bomb drops down from the aeroplane what will be the position of the bomb with respect to the plane?
There are two forces on the bomb when it is dropped; horizontal, and vertical. The vertical force is gravity, and the horizontal force is the velocity of the plane when the bomb is dropped. In order to determine how far away the bomb will drop from the initial point of release, it is necessary to know the height that the plane is at, and the velocity of the plane, which is also the initial horizontal velocity of the bomb (it is constant, neglecting air resistence.)
Discuss the motion of a body thrown from a certain height?
Ignoring air resistance, for simplicity:* The horizontal component of the velocity (if you give it an initial thrust in any direction that is not exactly down or up) will remain unchanged, until the object touches the ground. * The vertical component of the velocity will change at a rate of about -9.8 meters per second square (assuming you define positive numbers to mean upwards).

A plane can travel with a speed of 80 mi-hr with respect to the air determine the resultant velocity of the plane magnitude only if it encounters a 10 mi-hr headwind?
sol:- resultant velocity of a plane=80-10 =70m/s

What is the eqution for x component in a vector?
x = V times (cos A ) where V = vector magnitude and A = angle of vector to the x plane

Where is the vertical plane in earth?
A vertical plane is any plane where the normal (a line at 90 degrees to the plane) is horizontal. All your walls are vertical planes. The normal to the plane of the Earth's orbit is often used to define "up" and "down" for planet Earth. The Earth's axis is tilted at about 23.5 degrees away from this "vertical" line. Also you could define "vertical" as simply the direction shown by a plumb line. That's the definition which has walls as vertical planes. With either definition there will be more than one plane that is a vertical plane.
A novice pilot sets a plane's controls thinking the plane will fly at 2.5 X 102 kmh to the north if the wind blows at 75 kmh toward the southeast what is the plane's resultant velocity?
The wind is blowing at a vector of 225 degrees with a magnitude of 75. The original heading is on a vector of zero with a magnitude of 2500. The resultant vector is then 15 degrees east of north at 203.98 kmh.
What is the velocity of a plane traveling nothwest at 610 mph?
Velocity is the rate of speed in a given direction. Therefore, the plane's velocity is 610mph NW.
What is the plane's velocity if it travels 100 km in 90 minutes?
The definition of velocity, or at least speed, is distance/(time at speed), in this instance 10/9 km/min. (In advanced mathematics, "velocity" is a vector quantity, with both a magnitude and a direction. In that instance, a direction would also be needed but was not stated in the problem.)
What is the difference between coronal plane and sagittal plane?
sagittal plane is a vertical plane that divides sth to left and right parts coronal plane is a vertical plane that divides sth into anterior and posterior parts
