Question

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

a. Mercury

b. Mars

c. Saturn

d. Pluto

Answer 1

Answer:

a) $W_{Mercury}=92.5 N$

b) $W_{Mars}=92.8 N$

c) $W_{Saturn}=261.0 N$

d) $W_{Pluto}=15.5 N$

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!
