a 10-kg object traveling at 6 m/s collides head on with a 2-kg object at rest. What is the total momentum of the system after the collision?

Answers

Answer 1

Answer:

M1V1i+M2V2i=(M1 + M2)vf

(10)(6)+(2)(0)=(10+2)vf

60=12vf

60÷12 =12vf÷12

5=vf

::Vf=5ms-1 to the right

What is an Absolute value function?

An absolute value function is a function that gives positive value for a number or variable. It has a V shaped graph, it is also called as a modulus function.

The absolute function is y = | -x +7| +-4

The v shaped curve has a vertex and it can be determined by following method.

The value of the x coordinate is determined by equating the modulus to 0, the point at which the modulus is zero.

-x +7 = 0

Adding -7 to both sides.

-x = -7

x = 7

The value of y at this point is the y coordinate of the vertex.

y = 0 +4

y = 4

(x,y) = ( 7,4)

Paul is going to have the exterior of his home painted. Painting USA charges $75.00 to come out and evaluate the house plus $25.00 per hour of labor. Upscale Home Painting does not charge to evaluate the house. However, they charge $40.00 per hour.

The cost of painting the house will be the same for both companies if the number of hours required to paint Paul’s house is
A- 3 hours
B- 5 hours
C-8 hours

Answers

Answer:

The most cost effective company will be Painting USA that charge $700 to paint Paul house .

As given

Paul is going to have the exterior of his home painted.

Painting USA charges $75.00 to come out and evaluate the house plus $25.00 per hour of labor.

If it takes 25 hours to paint Paul’s house.

Total amount charge by Painting USA = Painting USA charges for come out  and evaluate the house + Cost of per hour of labor × Total hours take to paint Paul house .

Total amount charge by Painting USA = 75 + 25 × 25

                                                               = 75 + 625

                                                               = $ 700

As given

Upscale Home Painting does not charge to evaluate the house. However, they charge $40.00 per hour.

Total amount charge by Upscale Home Painting = Cost of per hour of labor × Total hours take to paint Paul house

                                                                                = 40 × 25

                                                                                = $ 1000

Therefore  the most cost effective company will be Painting USA  that charge $700 to paint Paul house .

Anne Kates house is 20c. She had just made a fresh cup of tea (100c). Five minutes after she made her mad scientist nephew came in,stuck a thermometer in the cup and announced that the tea was now only 70c Write the possible equation with asymptotes

Answers

Answer:

The possible equation is; T(t) = 20 + 80·[tex]e^{(-0.094 \cdot t)}[/tex]

The horizontal asymptotes is Lim(t → ∞), T → 20°C

The vertical asymptote is Lim(t → 0) T → 100°C

Step-by-step explanation:

The given parameters are;

The temperature of the house = 20°C

The initial temperature of the tea = 100°C

The temperature of the tea after 5 minutes = 70°C

From Newton's law of cooling, is given as follows;

[tex]T(t) = T_s + (T_0 - T_s) \cdot e^{k \cdot t}[/tex]

[tex]\dfrac{dT}{dt} = -k(T - T_a)[/tex]

Where;

T(t) = The temperature after time, t =

[tex]T_s[/tex] =The room temperature = 20°C

T₀ = The initial temperature of the tea = 100°C

k = Constant

T(5) = 70°C, therefore, we have;

[tex]70 = 20 + (100 - 20) \cdot e^{k \cdot 5}[/tex]

50/80 = [tex]e^{k \cdot 5}[/tex]

5·k = ㏑(5/8)

k = ㏑(5/8)/5 ≈ -0.094

Therefore, the possible equation is given as follows;

T(t) = 20 + 80·[tex]e^{(-0.094 \cdot t)}[/tex]

The asymptotes are Lim(t → ∞), T → 20°C  and Lim(t → 0) T → 100°C

Steve is playing a carnival game. He wants to win a prize, but he thinks he has about a 20% chance of winning. He uses the expression 0.2t to calculate the number of games he will need to play in order to win a prize.

If he plays the game 12 times, about how many times can he expect to win?

Answers

Answer:50%

Step-by-step explanation:

Steve's expected times of winning in 12 trials is about 2 times.

What is probability?

Probability is the chance of occurrence of a certain event out of the total no. of events that can occur in a given context.

The winning chance of Steve is 20% or 0.2.

We know, We know The expected value, also known as the expectation, average, is a generalization of the weighted average in the field of probability theory.

Informally, the anticipated value is the arithmetic mean of a significant number of outcomes of a random variable that were independently chosen.

Therefore, If he plays the game 12 times the number of times he is expected to win is,

= 12×0.2.

= 2.4 Or 2 times.
