Question

Your suitcase weighs 50 N. As you ride up an escalator toward the second floor, carrying that suitcase, you are traveling at a constant velocity. The upward force you must exert on the suitcase to keep it moving with you is?

Answer 1

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

$F_{net}=N-mg$

$ma=N-50$

Substitute a=0

$0=N-50$

$N=50$ N

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