Answer:
5. 7.452 min
Explanation:
Momentum is conserved, so:
m₁ u₁ + m₂ u₂ = m₁ v₁ + m₂ v₂
0 = (0.695 kg) (-12 m/s) + (59 kg) v
v = 0.1414 m/s
She is 63.2 m away, so the time it takes to reach the shuttle is:
t = 63.2 m / 0.1414 m/s
t = 447.1 s
t = 7.452 min

Answer:
Explanation:
First of all, let's convert everything into SI units:
n = 2.4 mol (number of gas moles)
(gas pressure)
(gas volume)
R = 8.31451 J/K · mol (gas constant)
The ideal gas equation states that
Solving for T, we find the gas temperature
And now we can find the average kinetic energy of the gas:
where
k = 1.38066 × 10−23 J/K is the Boltzmann's constant
Substituting,
