Explanation / Answer

The mass of Jack plus space suit, plus power pack, is 105.0 +24 =129 kg.

The initial momentum = 129kg *(-1m/s) = -129kgm/s.

Final mometum = 105*u - 24*3.1

Equating the initial and final momentum

105*u - 24*3.1 =-129

105*u = 54.6

u = -0.52 m/s

Minus sign shows that he is still moving away from the shuttle.
