Answer:
The constant 0.091 in the astronauts' equation of the best fit line is equal to 
The value of g on Mars is 
Explanation:
From the question we are told that
The line of best fit is defined by the equation 
Now the equation of a straight line is defined as
Now comparing the given equation to this we have that

Now from the graph the formula for the slope is

=> 
Now from the question we are told that

=> 
=> 
=> 
I believe that would be the second law of motion
