While traveling in a car, the centrifugal force a passenger experiences as the car drives in a circle varies jointly as the mass

rjkz [21]

Answer:

A- 129.6 N

Step-by-step explanation:

Since the centrifugal force on the passenger, F varies jointly as the mass of the passenger, m and the square of the speed of the car,v. In mathematical notation, F ∝ mv² ⇒ F = kmv².

If F₁ = 226.8 Newtons, m₁ = 70 kilograms and speed v₁ = 60 kilometers per hour. From F= kmv², k = F/mv² the proportionality constant. If F₂ is the force on the passenger of mass m₂ = 90 kilograms and speed of car ,v₂ = 40 kilometers per hour. Then,

$k = \frac{F_{1} }{m_{1}v_{1} ^{2} } = \frac{F_{2} }{m_{2}v_{2} ^{2} }\\ F_{2} = F_{1} \frac{m_{2} }{m_{1} }(\frac{v_{2} }{v_{1} }) ^{2} \\F_{2} = 226.8\frac{90 }{70 }(\frac{40 }{60 }) ^{2}\\F_{2} = 129.6 newtons$

Find four numbers proportional to the numbers 2, 4, 5, and 6 if the difference between the sum of the two last numbers and the s

Nat2105 [25]

Number 1 wants you to set up proportions so four numbers equal to 2/1 would be: 6/3 8/4 10/5 12/6, and so on. I'm not sure what they're asking when they say the sum of the first two numbers is equal to 4.8

Solve the equation. Show all work.<br> -2 (4 - x) = 12x – 3<br> (I think this is 9th grade algebra)

Genrish500 [490]

Answer:

-1/2

Step-by-step explanation:

-2 (4 - x) = 12x – 3

-8+2x=12x-3

+8 +8

2x=12x+5

-12x -12x

-10x=5

/-10 /-10

= -1/2
