                         N{\'o}s propomos um mecanismo de transfer{\^e}ncia de momento 
                         entre as ICMEs e o vento solar que a circunda que desacelera as 
                         ICMEs r{\'a}pidas (V_cme > V_sw). Neste caso, a 
                         desacelera{\c{c}}{\~a}o envolve a a{\c{c}}{\~a}o de

                         velocidade da ICME versus a dist{\^a}ncia percorrida e

                         o coeficiente de arrasto, (C_d), e o coeficiente da viscosidade

                         description of the lnterplanetary Coronal Mass Ejections (ICMEs) 
                         dynamics in their travel from Sun to Earth. We propose a mechanism 
                         of momentum transfer between ICMEs and the surrounding solar wind 
                         that decelerate the fast ICMEs (V_cme > V_sw). In this case, the 
                         deceleration involves viscous forces acting between the ICME and 
                         the surrounding medium. We solve the differential equations that 
                         describe the process using differcnt expressions for the viscous 
                         force. We find solutions that include the variability of the ICME 
                         radio and the mass density of the medium and find out the speed 
                         behavior of the ICMEs versus the traveled distance. We present the 
                         analytical solutions with the corresponding in situ and remote 
                         data analysis and discuss the implications of the different 
                         parameters involved in this mechanism of momentum transfer. We 
                         consider the ICME mass, (m_cme), the density ofthe interplanetary 
                         medium, the solar wind speed, (V_sw), the exponent of radial 
                         expansion of the ICME, (p), the drag coefficient, (C_d), and 
                         kinematic viscous coefficient, (v).",
