The maximum velocity of the car is 0 m/s and the time t' when it stops is t' = -10/a when subjected to acceleration.
Given that the jet car is originally traveling at a velocity of 10 m/s and is subjected to acceleration, we need to determine the car's maximum velocity and the time t' when it stops.
We can use the equation of motion:
v = u + at
Where:
v = final velocity
u = initial velocity
a = acceleration
t = time
Let's assume that the car comes to a stop at time t' and the final velocity is 0 m/s.
0 = 10 + at'
t' = -10/a
Now, to determine the maximum velocity, we can use another equation of motion:
[tex]v^2 = u^2 + 2as[/tex]
Where:
s = distance
As the car stops, the distance traveled before coming to a stop will be:
[tex]s = ut' + (1/2)at'^2[/tex]
Substituting the value of t' in the above equation, we get:
[tex]s = 10(-10/a) + (1/2)a(-10/a)^2[/tex]
s = -50/a
Now, substituting the values of s, u, and a in the equation of motion, we get:
[tex]v^2 = 10^2 + 2a(-50/a)[/tex]
[tex]v^2 = 100 - 100\\v^2 = 0[/tex]
v = 0 m/s
Hence, the maximum velocity of the car is 0 m/s and the time t' when it stops is t' = -10/a.

Answer:
28 litres of mango juice will be required
Step-by-step explanation:
11). b. Internal dimensions of the rectangular prism are,
Length = 40 cm
Width = 20 cm
Height = 35 cm
Volume of the rectangular prism = Length × Width × Height
= 40 × 20 × 35
= 28000 cm³
Since, 1 cm³ = 1 mL
Therefore, 28000 cm³ = 28000 mL
Since, 1000 mL = 1 L
28000 mL = 28 L
Therefore, to fill this jar 28 L of orange juice will be required.

The best way to do this is to write it out, but with large ones like this you should use the equation:
C(n,r) = n!/(r!(n-r)!),
where:
C(n,r) is the number of combinations;
n is the total number of elements in the set; and
r is the number of elements you choose from this set.

Find the surface area of the
triangular prism.
10 ft.
3 ft.
3 ft
Given:
The figure of a triangular prism.
To find:
The surface area of the triangular prism.
Solution:
We know that, a triangular prism contains 2 congruent triangular surface and 3 rectangular surface.
Triangles have base 3 ft and height 2 ft.
Area of a triangle is
[tex]Area=\dfrac{1}{2}\times base\times height[/tex]
[tex]A_1=\dfrac{1}{2}\times (3)\times (2)[/tex]
[tex]A_1=3[/tex]
Area of congruent triangles are congruent. So,
[tex]A_1=A_2=3\text{ sq. units}[/tex]
Now the three rectangular surface have dimensions 10 by 3, 10 by 3 and 10 by 3 because the triangles are equilateral and the length of the prism is 10 ft.
Area of a rectangle is
[tex]Area=Length\times width[/tex]
[tex]A_3=10\times 3[/tex]
[tex]A_3=30[/tex]
Dimensions of all three rectangles are same, therefore there areas are equal.
[tex]A_3=A_4=A_5=30[/tex]
Now, the total surface area of the prism is
[tex]A=A_1+A_2+A_3+A_4+A_5[/tex]
[tex]A=3+3+30+30+30[/tex]
[tex]A=96[/tex]
Therefore, the total surface area of the prism is 96 sq. ft.

how to the medium in the dot line????!! I don't want my mom to be mad at my grade please!!!!!!
Thank you whoever helps me!
Answer: To find the median, count the dots from left to right until you find the middle value.
Step-by-step explanation:
Ok so first it's not a dot line it's a dot plot. Second, let's define what a medium is. The medium is the "middle" of a sorted list of numbers. To find the Median, place the numbers in value order and find the middle number. Example: find the Median of {13, 23, 11, 16, 15, 10, 26}. The middle number is 15, so the median is 15. Tip to find the median from a list of value ordered numbers every time cross a number from each side. For example, if you cross 13 from above also cross 26 and if you cross 23 then also cross 10.
Back to your original question of how to find the medium on a dot plot you need to take all the numbers from your dotted line put them in order even if they are repeated and then cross each one on each side from right to left. Also remember if you cross out all the numbers right and left and end up with two numbers left then take them and add them and then divide by 2 and that will be the median.
An example is attached on here in order to help you understand what I am saying. Hope this helps. Your welcome and I hope you make your mama proud.

The school took in $71 on the second day by selling 2 adult tickets and 7 student tickets. Define two variables for this situation. Write a system of equations to represent this situation. What is the price each of one adult ticket and one student ticket?
Answer:
Your answer.
8x + y = 95.........(1)
2x + 7y = 71........... (2)
Y = 95-8x........ (3)
Put this value in eq 2
Then x = 11
Put x value in eq 3
Y = 7
