A meteoroid is moving towards a planet. It has mass m= 0.18x10⁹ kg and speed v1 = 5.9x10⁷ m/s at distance R1 = 2.9x10⁷ m from th
anzhelika [568]

Answer:

5.90000114e+7 m/s

Explanation:

Given values

M₁ = 1.8e+8 kg

M₂ = 2.4e+25 kg

M = M₁ + M₂ = 2.400000000000000018e+25 kg

G = 6.6743e-11 m³ kg⁻¹ sec⁻²

GM = 1.60183200000000001201374e+15 m³ sec⁻²

r₁ = 2.9e+7 m

v₁ = 5.9e+7 m/s

R = 2.2e+6 m

The total energy of the meteroid per unit mass at time t₁ is

E/M₁ = 0.5v₁² − GM/r₁ = 1.7404999447644137931034478615952e+15 m²/s²

At impact,

E/M₁ = 0.5v₂² − GM/R = 1.7404999447644137931034478615952e+15 m²/s²

v₂ = √[2(E/M₁ + GM/R)] = 5.9000011404572937396882314817886e+7 m/s

v₂ − v₁ ≈ 11.4 m/s

Alenkinab [10]

Answer:

h=17357.9m

Explanation:

The atmospheric pressure is just related to the weight of an arbitrary column of gas in the atmosphere above a given area. So, if you are higher in the atmosphere less gass will be over you, which means you are bearing less gas and the pressure is less.

To calculate this, you need to use the barometric formula:

P=P_0e^{-\frac{Mg}{RT}h}

Where R is the gas constant, M the molar mass of the gas, g the acceleration of gravity, T the temperature and h the height.

Furthermore, the specific gas constant is defined by:

R_{H_2}=\frac{R}{M}

Therefore yo can write the barometric formula as:

P=P_0e^{-\frac{g}{R_{H_2}T}h}

at the surface of the planet (h =0) the pressure is P_0[\tex]. The pressure at the height requested is half of that:[tex]P=\frac{P_0}{2}

applying to the previuos equation:

\frac{P_0}{2} =P_0e^{-\frac{g}{R_{H_2}T}h}

solving for h:

h=17357.9m
