The horizontal velocity of a projectile is constant (a never changing in value), There is a vertical acceleration caused by gravity; its value is 9.8 m/s/s, down, The horizontal motion of a projectile is independent of its vertical motion.

## What is the horizontal component of a vector?

The horizontal component stretches from the start of the vector to its furthest x-coordinate. The vertical component stretches from the x-axis to the most vertical point on the vector. Together, the two components and the vector form a right triangle.

## How do you solve horizontal and vertical forces?

Assume that the chain is exerting a 60 N force upon Fido at an angle of 40 degrees above the horizontal. A quick sketch of the situation reveals that to determine the vertical component of force, the sine function can be used and to determine the horizontal component of force, the cosine function can be used.

## What does it mean to say a projectile’s horizontal and vertical velocity are independent of each other?

what does it mean to say that the horizontal and vertical components of a projectile’s velocity are independent of each other? The vertical velocity is not constant; it changes since gravity causes acceleration in the vertical direction.

## What objects are considered projectiles?

An object that is thrown vertically upward is also a projectile (provided that the influence of air resistance is negligible). And an object which is thrown upward at an angle to the horizontal is also a projectile (provided that the influence of air resistance is negligible).

## What is the vertical component of the velocity just before it hits?

When a projectile reaches maximum height, the vertical component of its velocity is momentarily zero (vy = 0 m/s).

## What is the velocity of the ball?

Conclusion: The magnitude of the velocity of the ball is 26.3 m/s for the parabolic motion just before it hits the ground and this greater than the 17.1 m/s for the velocity of the ball that falls straight downward.

## What is the formula for horizontal projectile motion?

Horizontal projectile motion equations Horizontal distance can be expressed as x = V * t . Vertical distance from the ground is described by the formula y = – g * t² / 2 , where g is the gravity acceleration and h is an elevation.
