Two astronauts are floating, at rest, face-to-face in deep space.
Astronaut A has a mass of 75 kg75\text{ kg}75 kg and astronaut B has a mass of 120 kg120\text{ kg}120 kg.
Astronaut A pushes against astronaut B with a force of 60 N60\text{ N}60 N.
What does Newton’s third law tell us about the force that astronaut A experiences from astronaut B?
Calculate the acceleration of astronaut B when they are pushed with the force of 60 N60\text{ N}60 N. Use the equation: force=mass×acceleration\text{force} = \text{mass} \times \text{acceleration}force=mass×acceleration
State the total momentum of both astronauts before astronaut A pushes astronaut B.
After pushing astronaut B, astronaut A has a velocity of 1.6 m/s1.6\text{ m/s}1.6 m/s. Calculate the momentum of astronaut A. Use the equation: momentum=mass×velocity\text{momentum} = \text{mass} \times \text{velocity}momentum=mass×velocity
Calculate the velocity of astronaut B after being pushed by astronaut A.
