B: Extension Lines! You could have just searched this up on google
It’s either C or D. let me know but I would do C!
Answer:
2.4 m/s". 1
Explanation:
A jet with mass m = 8 x 10* kg jet accelerates down the runway for takeoff at 2.4 m/s". 1
<span> it CAN be negative if you consider the velocity as "vector". It CANNOT if you consider the "numerical" velocity..</span>
Answer:
The equilibrium points include
x₁ = - 1.177
x₂ = 0
x₃ = 1.177
Explanation:
At equilibrium, the sum of forces acting on a body is equal to zero.
F(x) = ax (b − cx²) [a = 8.97, b = 7.83, c = 5.65]
F(x) = (abx - acx³)
= (8.97×7.83)x - (8.97×5.65)x³
F(x) = 70.2351x - 50.6805x³
At equilibrium, F(x) = 0
70.2351x - 50.6805x³ = 0
x(70.2351 - 50.6805x²) = 0
x = 0 or (70.2351 - 50.6805x²) = 0
70.2351 - 50.6805x² = 0
50.6805x² = 70.2351
x² = (70.2351/50.6805)
x² = 1.385840708
x = ± 1.177
So, x = -1.177, 0 and 1.177
x₁ = - 1.177
x₂ = 0
x₃ = 1.177
Hope this Helps!!!
