Answer: A projectile reaches its highest point when its vertical velocity component is zero.
Step-by-step explanation:
In projectile motion, objects moves in parabolic path.
Projectile motion is a type of motion in which an object moves in a bilaterally symmetrical, parabolic path. Projection motion happens when the force is applied at the start of the trajectory (where the object follows) which follows an interference which is gravity. Gravity takes over and afterwards the object accelerates downwards. The acceleration is constant so the vertical velocity (Vy) varies linearly. The maximum height of the projectile which is the highest height is reached when the vertical velocity (Vy) is equal to zero.
After the projectile reaches its maximum height which is its highest point, it begins to drop downwards.
Okay, don’t freak out. It’s more simple than it seems.
To find the area of this rectangle you use length x length
Let’s look for the length first
Use the bottom left and right points
(-2.25,-1) and (2.25,-1)
The length is a horizontal line so we use the x-coordinates. The distance from -2.25 to 2.25 is 4.5
Now let’s find the height. Let’s use the top left and bottom left coordinates.
(-2.25,4) and (-2.25,-1)
The height is a vertical line. The y-coordinates. Their difference is 5.
So 4.5 x 5 = 22.5
Answer:
5, 7, 9, 11
Step-by-step explanation:
Solve the inequality
w - 4 < 8 ( add 4 to both sides )
w < 12
w ∈ { 5, 7, 9, 11 }
