Question

How much The mass of an astronaut with all of his gear oxygen tank and suit if he is in a rocket an acceleration of 5.5 m/s2 to and flying with a force of 1100 needs it so your work

Answer 1

From Newton's Second Law of Motion, we know that if a force F acts over a particle with mass m, it will accelerate at a rate a given by the equation:

$F=ma$

In the problem, the force and the acceleration of the astronaut are given. Isolate m from the equation and replace F=1100N and a=5.5m/s^2 to find the mass of the astronaut:

$\Rightarrow m=\frac{F}{a}=\frac{1100N}{5.5\frac{m}{s^2}}=200kg$

Therefore, the mass of the astornaut including his/her gear is equal to 200kg.
