An airplane needs to reach a velocity of 203.0 km/h to take off. On a 2000 m runway, what is the minimum acceleration necessary
Aliun [14]

Answer:

1.59 m/s²

Step-by-step explanation:

Acceleration = change in Velocity over time. Mathematically it is represented as Δv/Δt

Given values in the question:

  • Final velocity 203.0 km/h which is equal to (203/3.6)m/s = 56.39 m/s
  • distance 2000 m
  • Initial velocity is 0 m/s

<em>To use the equation for acceleration time is needed.</em>

<em>velocity= distance/time</em>

(203/3.6) = 2000/time  <em>mltiplying both sides by time</em>

(203/3.6) x time = 2000 <em>making time subject of the formula</em>

time = 2000/(203/3.6)

time = 35.47 seconds

Substituting into the acceleration equation

acceleration =Δv/Δt

                      =(56.39- 0)/35.47

                       = 56.39/35.47

                       =1.59 m/s²

write The equation of the line that passes through the point parentheses (6 , 4) and is parallel to the equation 2X plus 3Y equa
aliina [53]

Answer:

2x + 3y - 24 = 0

Step-by-step explanation:

2x + 3y = 18

3y = -2x + 18

y = \frac{-2}{3}x + 6

m = -2/3

y - 4 = -2/3(x - 6)

3y - 12 = -2x + 12

2x + 3y - 24 = 0
