The formulas used to analyze the horizontal and vertical motion of projectiles launched at an angle involve the use of tangent, cosine and sine.
<h3>
What is vertical motion of a projecile?</h3>
The vertical motion of a projectile is affected by gravity and the velocity of vertical motion given by the following formula;
Vy = Vsinθ
<h3>
What is horizontal motion of a projecile?</h3>
The horizontal velocity of a projectile is given by the following formula;
Vx = Vcosθ
<h3>Direction of the motion</h3>
The direction of the motion is calculated as follows;
tanθ = Vy/Vx
Thus, the formulas used to analyze the horizontal and vertical motion of projectiles launched at an angle involve the use of tangent, cosine and sine.

A) -3.75 meters/second
A=(20^2-80^2)/(2x800)
=(400-6400)/1600
=-6000/1600
=-3.75
B) 16 seconds
t=(20-80)/-3.75
=-60/-3.75
=16
Answer:
Bad things
Explanation:
Global warming has many terrible effects on people and the earth itself
such as, death, birth defects, asthmea, breathing conditions, increased diseases.
Answer:
The answer is 
<em> pounds</em>
Explanation:
We will start this question by representing the force vectors in Cartesian coordinate system:
- Force 1 acting on the right
- Force 2 acting upward
- Force 3 acting at 45°
Let the single force we need be represented by 
Since, the body is in equilibrium the summation of all the forces acting on it should be zero:
∑
(Sum of all forces in 
direction is equal to zero)
( component of force 3 is negative because it is acting in opposite direction)
∑
(Sum of all forces in 
direction is equal to zero)
( component of force 3 is negative because it is acting in opposite direction)
So,
Hence, to get the scalar quantity of a single force:
![F=\sqrt[2]{(0.1213)^{2}+(-2.8786)^{2} }](https://tex.z-dn.net/?f=F%3D%5Csqrt%5B2%5D%7B%280.1213%29%5E%7B2%7D%2B%28-2.8786%29%5E%7B2%7D%20%20%7D)
<em> pounds</em>
