At sea level, an argon atom in the air has an average kinetic energy of 5.59×10-21 J. Its mass is 6.64×10-26 kg. The argon atom shoots straight up without colliding with the molecules in the air. (Assume that you can use g = 9.81 m/s2; although we'll see in Chapter 12 that this assumption may not be justified for this situation.)
a) How high would it rise?
b) What percentage of the Earth's radius is this height?
c) What is the argon atom's initial speed?
