A 63 kg astronaut is on a spacewalk when the tether line to the shuttle breaks. The astronaut is able to throw a spare 10.0 kg oxygen tank in a direction away from the shuttle with a velocity of 12 m/s, propelling the astronaut back toward the shuttle. Assuming the astronaut starts from rest, find the astronaut’s final speed after O mjs the tank is thrown. t? p . 1D 0 V 1 r | ( 2 rv\ 5 , VYl , \T + l/ > i 0.015 kg ^ ^ fYNV , + ' ( c,?> ^ i - rv\ { s ray A marble moves to the right at 22.5 cm/s on a frictionless surface and makes an elastic heacPon collision with a 0.025 kg marble moving to the left at 18 cm/s.
