1. The problem statement, all variables and given/known data
Two identical eggs of mass 0.1 kg are dropped from rest at height h. One is dropped on Earth and the other on the surface of the moon. Egg dropped on earth experiences a force due to air resistance (F=-kv) where v is velocity of egg and k is constant of proportinality equal to Ns/m. No forces of resistance on the moon.

Gravity on earth = 9.81 m/s^2 Gravity on moon = 1.62 m/s^2

2. Relevant equations

What is terminal velocity of the egg falling through Earth’s atmosphere?
From what height will the eggs hit the ground at the same speed?
Should the value of k at a high altitude be >, <, or = to k at sea level and why?

Hello Jasonmoon, Welcome to Physics Forums.

What you've written under Relevant Equations is just more of the problem statement, so you should look to identify some equations that you think might be relevant to the problem at hand. You also need to provide some attempt at solving the problem so that we can see what you know about the subject and where you need help. We do not do your homework for you here; you need to show the effort.
