The average KE per molecule (also per atom in this case) is constant. Look up the atomic masses of neon and argon, m(Ne) and m(Ar). v = sqrt(2KE/m) ==> v(Ar) = v(Ne)*sqrt(m(Ne)/m(Ar)).

The energy from the banana must be converted to Joules So 100kcal= 100000cal*4.184J/cal = K = 1/2*m*v^2 so v = sqrt(2*K/m) This is where your eqn is in error So v = sqrt(2*418400/82) = 101m/s
