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.
