Use Newton's law of gravity to compute a 50-kg person's weight on Mars.

Use Newton's law of gravity to compute a 50-kg person's weight on the asteroid Ceres.

Use Newton's law of gravity to compute a 50-kg person's weight on Jupiter (neglecting temporarily the absence of a solid surface on this planet!).

Answer:

Given that

1)

Mass ,m = 50 kg

As we know gravity on the earth surface g

[tex]g=9.81\ m/s^2[/tex]

So the wight of person on the earth,W

W= m g

W = 50 x 9.81

W=490.5 N

2)

Mass ,m = 50 kg

As we know gravity on the Mars surface 0.38 g

[tex]g=0.38\times 9.81\ m/s^2[/tex]

[tex]g=3.72\ m/s^2[/tex]

So the wight of person on the Mars surface,W

W= m g

W = 50 x 3.711

W=186.3 N

3)

Mass ,m = 50 kg

As we know gravity on the  asteroid Ceres g

[tex]g=0.27\ m/s^2[/tex]

[tex]g=0.27\ m/s^2[/tex]

So the wight of person on the asteroid Ceres,W

W= m g

W = 50 x 0.27

W=13.5 N

4)

Mass ,m = 50 kg

As we know gravity on the   on Jupiter g

[tex]g=24.79\ m/s^2[/tex]

[tex]g=24.79\ m/s^2[/tex]

So the wight of person on the Jupiter ,W

W= m g

W = 50 x 24.79

W=1239.5 N
