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


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.
 
        
             
        
        
        
Answer:

Step-by-step explanation:
Let's solve your inequality step-by-step.
−5(w+4)+8<−42
Step 1: Simplify both sides of the inequality.
−5w−12<−42
Step 2: Add 12 to both sides.
−5w−12+12<−42+12
−5w<−30
Step 3: Divide both sides by -5.
