Question

How do you find the horizontal velocity?

Answer 1

Hint: The horizontal velocity that occurs when the object is in projectile motion projectile motion can be defined as it is the motion of an object thrown or projected into the air. The object is referred to as a projectile and its trajectory is called its direction.

Complete step by step solution:
When a particle or object is thrown obliquely near to the surface of the earth, it travels under constant acceleration along a curved path towards the middle of the earth if we assume the object to be remains close to the earth surface.

Here, projectile is called the direction of such an object and the motion is called projectile motion.

In the projectile motion air resistance to the body’s motion must be considered absent.
There are two simultaneous separate rectilinear motions in a positive motion.

Along the x-axis:- uniform velocity responsible for the particle horizontal travel.
In the y-axis:- uniform acceleration responsible for the motion of the particle vertically downwards.

As shown below let us consider a ball projected at an angle with respect to the horizontal x-axis with the original velocity u.

As shown in the figure point o is a point of the projection where the object start its projection with a velocity u.

Now horizontal component will be along x-axis hence we can write as
${{u}_{x}}=u\cos \theta $
When the horizontal component of the velocity.

Note:
As an approach to know how to calculate the horizontal component of the velocity we have seen the definition of the projectile motion in which there are two components of the velocity one is along x-axis which we called horizontal component and the other one is vertical component which is along y-axis.
