a car start from rest and accelerates at the rate of 2ms² for 5 seconds. it maintenance this velocity for another 5 seconds. it eventually undergoes a uniform deceleration and finally comes to rest after further 5 seconds. A) draw the velocity-time graph for the journey
B) find the acceleration and deceleration respectively,
C) find the total distance travelled during each stage.
D) find the average velocity over the entire period
Answers
Answer:
Acceleration = 2m/s ; deceleration = - 2 m/s
Distance covered :
Stage 1 = 25
Stage 2 = 50 m
Stage 3 = 25m
Average Velocity = 6.67 m/s
Step-by-step explanation:
Given that:
Acceleration = 2m/s
Final velocity, v
v = u + at
u = 0 (from rest)
v = 0 + 2(5)
v = 10 m/s
deceleration ;
Final velocity, v ;
v = u + at
v = 0 ( to rest)
0 = 10 + a * 5
0 = 10 + 5a
-5a = 10
a = 10 / - 5
a = - 2 m/s^2
Distance traveled during each stage :
Distance = speed * time
Stage1 = S = 0.5at^2 = 0.5 * 2 * 5^2 = 0.5 * 2 * 25 = 25 meters
Stage 2 = Distance = speed * time = 10m/s * 5 = 50 metres
Stage 3 = distance = S = 0.5at^2 = 0.5 * 2 * 5^2 = 0.5 * 2 * 25 = 25 meters
Average Velocity :
Total distance traveled / total time taken
(25 + 50 + 25)m / 15s
100m / 15 s
Average Velocity = 6.667 m/s

Emery earns money mowing his neighbors' lawns. He charges $1.25 per square yard for each lawn he mows. His neighbors, the Flores Family, hires Emery to mow their rectangular lawn. Emery records the dimensions of their lawn and calculates that he will charge them $21. The width of the Flores' rectangular lawn is 4 yards. What is the length, in yards, of the Flores' lawn?
Answers
Answer: 4.2 yards
Step-by-step explanation:
Let x = length of the Flores' lawn in yards.
Then, Area of lawn = 4x sq. yard [Area of rectangle = width x length , here width = 4 yds (given)]
Charge per square yard = $1.25
Charge for Flores lawn = 1.25 × (Area of lawn)
= 1.25 (4x)
= 5x
As per given,
[tex]5x=21\\\\\Rightarrow\ x=\dfrac{21}{5}\\\\\Rightarrow\ x=4.2[/tex]
Hence, the length of the Flores's lawn = 4.2 yards

Step-by-step explanation:
The population of algae in an
experiment has been increasing by 30%
each day. If there were 100 algae at the
beginning of the experiment, predict the
number of algae in 5 days.
First, complete the equation:
Future Amount = 100(1 +0.30)5
Solve. Round to the nearest whole number.
Future Amount = [ ? ) algae
Enter
Answers
Given:
Initial population = 100 algae
Growth rate = 30% per day.
Time = 5 days
To find:
The future amount of population.
Solution:
The exponential growth model is
[tex]y=a(1+r)^t[/tex]
where, a is the initial value, r is the rate of interest in percent and t is time period.
Substituting the given values, we get
[tex]y=100(1+\dfrac{30}{100})^5[/tex]
[tex]y=100(1+0.30)^5[/tex]
Now, solve this.
[tex]y=100(1.30)^5[/tex]
[tex]y=100(3.71293)[/tex]
[tex]y=371.293[/tex]
Therefore, the future value is 371.293 algae.
Answer:
Future amount rounded = 371
Step-by-step explanation:
I = Initial population = 100 algae
R = Growth rate = 30% per day.
T = Time = 5 days
[tex]Future Amount = I(1+r)^{t\\[/tex]
[tex]Future Amount = 100(1+0.30)^{5}[/tex]
[tex]Future Amount = 100(1.30)^{5}[/tex]
Future Amount = 371.293 = 371

A stack of books is 5 feet 5 inches high. How high is it in inches?
Answers
Well first, you have to know that there are 12 inches in a foot so, that's 12 / 3 = 4, so that means that for every foot, there are 4 books. The books are 5 feet tall so 4 x 5 = 20. Your answer is: 20 books are in a stack.
Answer:
Step-by-step explanation: I would do 5x12 because there are 12 inches in one foot so 5x12 is 60 so there is 60 inches
Todd and his friends are painting 5 equal sections of a wall. The wall is 10 feet tall but its length is unknown. Each section will be a different color, so they need to know the area if each section. Write a expression for the total area of the wall. Explain how you came up with your expression.
Answers
Answer:
50
Step-by-step explanation:
5×10=50
The equation for the area of the wall can be written as [tex](10\times L)=10\times (L_T+ L_1+L_2+L_3+L_4)[/tex].
Given to us:
Todd and his friends are painting 5 equal sections of a wall. So,
total number of sections wall has = 5,
Height of the wall = 10 feet,
Also, we know;
area of rectangle = length x breadth,
area of wall = length x height,
So,
Area of wall = Area painted by Todd and his friends
height of the wall x Total length of the wall =
height of the wall x length of the wall painted by Todd
+ height of the wall x length of the wall painted by friend 1
+ height of the wall x length of the wall painted by friend 2
+ height of the wall x length of the wall painted by friend 3
+ height of the wall x length of the wall painted by friend 4
Therefore,
[tex](10\times L)=(10\times L_T)+(10\times L_1)+(10\times L_2)+(10\times L_3)+(10\times L_4)[/tex]
taking 10 as common,
[tex](10\times L)=10\times (L_T+ L_1+L_2+L_3+L_4)[/tex]
Hence, the equation for the area of the wall can be written as [tex](10\times L)=10\times (L_T+ L_1+L_2+L_3+L_4)[/tex].

Osh wanted to buy a new shirt for a school dance. At the store, he couldn't decide between a purple plaid shirt and a scarlet striped shirt. Since the shirts were on sale for $19.95 each, Josh decided to buy them both. He saved a total of $9.10. If he saved the same amount on each shirt, what was the original price of each one?
Answers
Answer: $24.50
Step-by-step explanation:
Since the shirts were on sale for $19.95 each, both shirts would cost:
= $19.95 × 2
= $39.90
We are further told that he saved a total of $9.10. This means the original cost for both shirts would be:
= $39.90 + $9.10
= $49.00
Then, the original price for each one would be:
= $49.00 / 2
= $24.50
