Homework Statement
A spacecraft approaches the surface of an unfamiliar planet and finds that the pressure of the atmosphere 50 km above the surface is 2.0 × 10^5 Pa. As the spacecraft descends, it is found that the pressure of the atmosphere 40 km above the surface increases to 5.0 × 10^5 Pa. Estimate the pressure at the surface of the planet and hence decide whether it is safe for the spacecraft to land, assuming that the atmosphere is thin and isothermal, and that the spacecraft can withstand an external pressure of 1.0 × 10^7 Pa.
Homework Equations
P(z) = P(0)e^(-z/y)
The Attempt at a Solution
I know that pressure decreases exponentially with the increase in height
Any pointers on where to start would be appreciated as always!
