An astronaut with a mass of 80.70 kg is standing still on the surface of the Mars (Mars has an acceleration due to gravity of 3.80 m / s^2). How many pounds force is she exerting on the martian surface?

Respuesta :

Answer:

Force, F = 68.93 pounds

Step-by-step explanation:

Given that,

Mass of the astronaut, m = 80.70 kg

Acceleration due to gravity on Mars, [tex]a=3.8\ m/s^2[/tex]

The force acting on him is given by using second law of motion as :

[tex]F=m\times a[/tex]

[tex]F=80.70\ kg\times 3.8\ m/s^2[/tex]

F = 306.66 N

Since, 1 newton = 0.224 pound

F = 306.66 N = 68.93 pounds

So, 68.93 pounds force she exerts on the martian surface. Hence, this is the required solution.
