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

How can you prove a triangle is a right triangle?
Darina [25.2K]
Your answer would be option 2. Use the slope formula to see if any sides are perpendicular. This is because a right triangle must have 2 perpendicular sides that form a 90° angle for it to be a right triangle, so finding these would prove it.

What is the measure of angle SQR?​
Mademuasel [1]

Answer:

4x°= 4x18= 72°=measure of angle SQR

Step-by-step explanation:

6x +4x = 180

10x = 180

x = 180/10

x= 18°

because m L SQR =4x°

now place the value of x in the above equation

m L SQR = 4 x(18°)= 72°
