a. During a rocket launch, an astronaut experiences a “g-force” (actually anacceleration) of 3.0 gs [upward], which is equal to three times the accelerationdue to gravity. If the astronaut weighs 79.4 kg, what is her apparent weight duringthe acceleration?
b. When the astronaut enters the ISS (International Space Station), she is in “freefall,” where the only force acting on her is the force of gravity applied by theEarth. What happens to her true weight and her apparent weight as she entersthe ISS? Explain.

One way to do this is to exert a known force on an astronaut and measure the acceleration produced. Suppose a net external force of 57.5 N is exerted and the astronaut's acceleration is measured to be 0.880 m/s². Calculate her mass (in kg). kg By exerting a force on the astronaut, the vehicle in which they orbit experiences an equal and opposite force. Discuss how this would affect the measurement of the astronaut's acceleration. Propose a method in which recoil of the vehicle is avoided.arrow_forward
