//Variable declaration
Kb=1.38*10**-23; //boltzmann constant(J/k)
T=303; //temperature(K)
e=1.6*10**-19; //charge(c)
MH=2*1.008*1.67*10**-27; //mass(kg)
//Calculation
KE=3*Kb*T/(2*e); //kinetic energy(eV)
cbar=sqrt(3*Kb*T/MH); //velocity(m/s)
//Result
printf("kinetic energy is %.1e eV",KE)
printf("\n velocity is %.2f m/s",cbar)
//answer given in the book is wrong
