A man of mass m is standing in an elevator. The elevator is accelerating downward at g/k, where k>1 and g is the gravitation acceleration. If the force on the man by the elevator's floof jmg, where j is a constant and k= a/(b+cj), where gcd(|a|,|b|,|c|)=1, what is a+b+c? If k cannot be expressed in this form, say so.
