Find the force a 68.5 kg person would experience while standing on the surface of mars. mars has a mass of 6.43 x 1023 kg and a radius of 3.43 x 106m from its center to the surface.

The correct answer is F=249.82N.

Step-by-step explanation:

The expression for the gravitational force is as follows:

Here, M, m are the masses, G is the universal gravitational constant and r is the distance between masses.

It is given in the problem that a person having mass 68.5 kg experience a force while standing on the surface of mars.

Put m= 68.5 kg, , and in the above expression.

F=249.82 N

Therefore, the correct answer is F=249.82 N.

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3
