Question

How much would a 25 kg suitcase weigh on the surface of…?

a. Mercury

b. Mars

c. Saturn

d. Pluto

Answer 1

a)
`W_(Mercury)=92.5 N`

b)
`W_(Mars)=92.8 N`

c)
`W_(Saturn)=261.0 N`

d)
`W_(Pluto)=15.5 N`

Step-by-step explanation:

First of all, we need to remember the value of gravity acceleration on each planet.

`g_(Mer)=3.70 m/s^(2)`

`g_(Mar)=3.71 m/s^(2)`

`g_(Sat)=10.44 m/s^(2)`

`g_(Plt)=0.62 m/s^(2)`

The definition of weigh is the product between the mass and the gravity acceleration, therefore we will have:

a)
`W_(Mercury)=25*3.70=92.5 N`

b)
`W_(Mars)=25*3.71=92.8 N`

c)
`W_(Saturn)=25*10.44=261.0 N`

d)
`W_(Pluto)=25*0.62=15.5 N`

I hope it helps you!
