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.
Something is missing there is no given. But here are the given for this question:
Salary = $8.75 per hour
40 hour work week
52 work week per year
5 days of work per week
Gas mileage is 21 miles per gallon
Gas costs is 1.26 per gallon
Average speed is 45 miles per hour
Daily round trip to work and back home is 34 miles
a. Kevin’s annual salary is 8.75 per hour x 40 hour work week x 52 work week per year
= $18,200
b. Kevin will spend on fuel each week:
34 miles daily round trip x 5 day work week divided by 21 miles per gallon x 1.26 per gallon
= $10.20
c. Kevin will spend _ hours on commuting
= 34 miles is the daily round trip x 5 day work week divided by 45 miles average speed per hour
= 3.78 hours
Hope this helps!

Answer:
The expression which represents the quantity of tomatoes and red peppers to buy is $ 2.50 × T + $ 4 × R = $ 20
Step-by-step explanation:
Given as :
The total amount spend for soup = $ 20
The cost of Tomatoes = $ 2.50 per pound
The cost of Red peppers = $ 4 per pound
Let the quantity of tomatoes to be bought = T pound
The quantity of red peppers to be bought = R pound
So, According to question
$ 2.50 × T + $ 4 × R = $ 20
I.e The expression which represents the quantity of tomatoes and red peppers to buy is $ 2.50 × T + $ 4 × R = $ 20 . Answer
