Physics A metal ball and a rubber ball, both having the same mass, strike a wall normally with the same velocity. The rubber ball rebounds and the metal ball does not rebound. It can be concluded that Both suffer the same change in momentum The initial momentum of the rubber ball is greater than that of the metal ball The rubber ball suffers greater change in momentum The metal ball suffers greater change in momentum Both suffer the same change in momentum The initial momentum of the rubber ball is greater than that of the metal ball The rubber ball suffers greater change in momentum The metal ball suffers greater change in momentum ANSWER DOWNLOAD EXAMIANS APP
