Webparentheses is the dynamic amplification–the factor by which a load is amplified when suddenly imposed. Since the displacement and load are proportional the effective force carried by the beam during impact is the product of the dynamic amplification and the weight, W. Note that the dynamic amplification for V = 0 (Ek = 0 ) = 2: a load suddenly
