Answer:
The Astronaut' mass is 55.99 kg.
Explanation:
Given that,
The net external force acting on the Astronaut, F = 50 N
The acceleration of the Astronaut, [tex]a=0.893\ m/s^2[/tex]
It is required to find the Astronaut' mass. We know that the force acting on an object is given by :
F = ma
m is mass of Astronaut
[tex]m=\dfrac{F}{a}\\\\m=\dfrac{50\ N}{0.893\ m/s^2}\\\\m=55.99\ kg[/tex]
So, the Astronaut' mass is 55.99 kg.
Answer:
Explanation:
In an earth's orbit , astronauts are not weightless . They feel weightlessness
because they do not feel any reaction force from the floor . It happens because the whole space station and astronaut are falling with the same acceleration of g . So the floor of the space station do not provide any reaction force .
The given force is acting only on the astronaut and the acceleration given is with respect to the space station .
acceleration of astronaut = force / mass
mass = force / acceleration
= 50 / .893
= 55.99
56 Kg .
