Question

A person weighs 613 N on Earth.

1) What is their mass? 

 This person goes to Jupiter where gravity = 24.79 m/s².

2) What is their weight on Jupiter? 

Answer 1

 1) Weight is mass times the acceleration of gravity, i.e. W=mg.

Solving for m, you get

m=W/g=613 N/(9.81 m/s²)=62.5 kg (3 sig figs)

2)On Jupiter g is given as 24.79 m/s².

So W=mg =(62.5 kg)(24.79 m/s²)= 1550 N (3 sig figs)
