Question

Superman meets an asteroid in outer space and hurls it at 800 m/s, as fast as a bullet. The asteroid is a thousand times more massive than Superman. In the strip, Superman is seen at rest after the throw. Taking physics into account, what would be his recoil speed (in km/s)?

Answer 1

mass of supesman , mi mass of astesoid, m'- 100 om. Speed of asteroid o'=8oomys. Let, o be speed of Supesman aftes the throw. As, they are initially at sest, initial momentum P o, momentum consesration final mom momentuna Using 7 Pf o. met me mer on, moa OM mv - 10oom X 800 ba (ice. in opposite direc- tion) 8x105 mys 8x102 Kms. So, Recoil relocity of superman is soa ON, oa 8x10² kr/s =800kongs,
