Answer:
The answer is 3.33m
Explanation:
The acceleration "a" is constant.
Acceleration is the variation of velocity over time,
.
solving the last equation
,
where 
because the airplane starts from rest.
Once again, velocity is the variation of distance over time.
then
where 
if we consider the end of the runway as the initial point (this step is for simplicity but you can let it expressed, it's going to cancel anyway).
If 
at 
, then
and the final expression for the distance is
.
If t = 2s, x = 4.44 m. Which means thad the additional distance is
Answer:
(a) 4.38 s.
(b) 1.817 s
Explanation:
(a)
Using
θ = ω₀t +1/2αt² ................ Equation 1
Where θ = number of revolution, t = time, α = angular acceleration, ω₀ = angular velocity.
Given: θ = 1.59 rev = 1.59×2π = 9.992 rad, ω₀ = 0 rad/s, α = 1.04 rad/s².
Substitute into equation 1
9.992 = 0(t) + 1/2(1.04)(t²)
t² = (2×9.992)/1.04
t² = 19.984/1.04
t = √(19.215)
t =4.38 s.
(b)
also using
θ = ω₀t +1/2αt²............... Equation 1
Given: θ =3.18 rev = 3.18×2π = 19.97 rad, ω₀ = 0 rad/s, α = 1.04 rad/s².
Substitute into equation 1
19.97 = 0(t) + 1/2(1.04)(t²)
t² = 19.97×2/1.04
t = √(38.40)
t = 6.197 s
The time require = 6.197-4.38 = 1.817 s
The taiga biome is a forest biome it has wet summers and long cold winters. The tundra, yes is considered a cold biome. But I do not think the taiga biome is a cold biome since it is a forestial biome. Also many plants grow in a taiga biome specifically Boreal and Coniferous forest plants. I believe it is false.
