Answer:

50 N

Explanation:

We are given that

Weight of suitcase=50 N

You are travelling at constant speed

Therefore,acceleration ,a=0

We have to find the upward force exert by you in the suitcase.

We know that

Net force=Normal-weight

[tex]F_{net}=N-mg[/tex]

[tex]ma=N-50[/tex]

Substitute a=0

[tex]0=N-50[/tex]

[tex]N=50[/tex] N

Hence, the upward force must you exert on the suitcase to keep it moving with you=50 N
