Answer:
time tt = 40.76 s
Explanation:
In this exercise we can find the acceleration time, the speed with which the acceleration ends and the rise and flight time
For all these calculations we can use vertical launch kinematics
The speed for maximum height is zero
v² = v₀² - 2 g y
v₀ = √ 2gy
v₀ = √ (2 9.8 980)
v₀ = 138.59 m / s
The time it takes to climb after finishing the acceleration is
v = v₀ - gt
t₁ = v₀ / g
t₁ = 138.59 / 9.8
t₁ = 14.14 s
The acceleration time is
v = v₀ + a t₂
As part of the rest the initial speed is zero
t₂ = v / a
t₂ = 138.59 / 16
t₂ = 8.66 s
The height raised at this time is
y₂ = v₀ t + ½ a t²
y₂ = 0 + ½ 16 8.66²
y₂ = 600 m
Let's look for the descent time, the height of the rocket is
y = y₂ + y₁
y = 600 + 980
y = 1580 m
y = v₀t + ½ g t²
v₀ = 0
t₃ = √ 2y / g
t₃ = √ (2 1580 / 9.8)
t₃ = 17.96 s
Total flight time is
tt = t₁ + t₂ + t₃
tt = 14.14 + 8.66 + 17.96
tt = 40.76 s
The intestines are part of the digestive system of the body. They are sometimes called the guts or bowels. This system deals with all the food and drink that you take into your body.
