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.
Answer:
Fourth option: 30 days
Step-by-step explanation:
We three path to complete the project:
Path A:
A1 → A2 → A3
10 days → 8 days → 9 days = 27 days
Path B:
B1 → B2 → B3
2 days → 7 days → 3 days = 12 days
Path C:
C1 → C2 → C3
10 days → 8 days → 12 days = 30 days
Then the duration of the critical path is 30 days, we can't conclude the project until each path has finished

-A rectangle's area is given by:
Given A=
and 
, we substitute in the formula to solve for the width as follows:
Hence , the rectangle's width is 
Answer:
Step 1: Distribute 
to 
and 
Step 2: Subtract from both sides of the equation 
Step 3: Add to both sides of the equation 
Step 4: Divide both sides of the equation by 
Step-by-step explanation:
Step 1: Apply the Distributive Property. Then you must distribute to and
Then:
Step 2: You must apply the Subtraction property of Equality and subtract from both sides of the equation. Then:
Step 3: You must apply the Addition property of Equality and add to both sides of the equation. Then:
Step 4: You must apply the Division property of Equality and divide both sides by . Then:
