Brielle Boyd · Answer 1

mass of astronaut, M = 66.5 kg

mass of tool, m = 2.3 kg

velocity of tool, v = 3.10 m/s

Let the velocity of astronaut is V.

(A) According to the conservation of moemntum

Momentum of astronaut = Momentum of tool

M x V = m x v

66.5 x V = 2.3 x 3.10

V = 0.107 m/s

(B) The direction of motion of astronaut is opposite to the direction of motion of tool.
