The comparison of the kinetic energy of the given bodies is required.
The first car has 16 times more the kinetic energy of the second car.
Kinetic energym = Mass of car = 4000 pound
[tex]v_1[/tex] = Initial velocity of car = 40 miles/hour
[tex]v_2[/tex] = Final velocity of car = 10 miles/hour
The mass of the car is constant so we have the relation
[tex]K\propto v^2[/tex]
Thus,
[tex]\dfrac{K_1}{K_2}=\dfrac{v_1^2}{v_2^2}\\\Rightarrow K_1=K_2\dfrac{40^2}{10^2}\\\Rightarrow K_1=16K_2[/tex]

1. Let's use pemdas
16*1/2= 8
32 / 4 * 8 - 2
8*8 - 2
64 - 2
= 62
2. Let's use pemdas

Write the equation of the line in slope-intercept form using y=mx+b
Answer:
y = -1/2x -7
Step-by-step explanation:
. The slope of the line (rise over run) goes down so it's negative and it you go down (bc it's negative slope) 1 and go over 2 so it would be -1/2
. B stands for the y intercept so it would be -7 because the line goes through -7 on the vertical line.

Answer:
3n−32=7n+28
n=-15
Step-by-step explanation:
Let's solve your equation step-by-step.
3n−32=7n+28
Step 1: Subtract 7n from both sides.
3n−32−7n=7n+28−7n
−4n−32=28
Step 2: Add 32 to both sides.
−4n−32+32=28+32
−4n=60
Step 3: Divide both sides by -4.
−4n/−4=60/−4
n=−15

A jar contains nickels and dimes. There is a total of 200 coins in the jar and their value is $14.55. How many dimes are in the jar?
Plz show the steps
Answer:
There are total of 80 dimes in the jar cuz...
n + d = 200 = n = 200 - d
0.05n + 0.1d = $14.00
0.05(200 - d) + 0.1d = $14.00
10 - 0.05d + 0.1d = $14.00
10 + 0.05d = $14.00
-10 -10
0.05d = $4.00
0.05d / 0.05 = $4.00 / 0.05
d = 80

Answer:
y = 0,4x -1 or y = 2/5 x -1
Step-by-step explanation:
you can use the slope formula
m = y2-y1 / x2-x1
m = -1 - (-3) / 0 - (-5) = 2/5
Answer:
y = 2/5x - 1
Step-by-step explanation:
Points on the graph: ( -5, -3) and (0, -1)
Slope:
m=(y2-y1)/(x2-x1)
m=(-1+3)/(0+5)
m = 2/5
Slope-intercept:
y - y1 = m(x - x1)
y + 3 = 2/5(x + 5)
y + 3 = 2/5x + 2
y = 2/5x - 1
