We will use Newton's second law

  • F=ma
  • m=F/a

#1

  • m=5/5=1kg

#Box 2

  • m=5/0.75
  • m=6.67kg

#Box 3

  • 5/4.3
  • m=1.16kg

First box has smallest mass

Answer:

Box 1

Step-by-step explanation:

Formula we are using :

Force = mass × acceleration

or

mass = Force / acceleration (since mass needs to be found)

=============================================================

Box 1 :

⇒ mass = 5 N / 5 m/s²

⇒ mass = 1 kg

=========================================================

Box 2 :

⇒ mass = 5 N / 0.75 m/s²

⇒ mass = 5 × 4/3 = 20/3 kg

⇒ mass = 6.67 kg

===========================================================

Box 3 :

⇒ mass = 5 N / 4.3 m/s²

⇒ mass = 50/43 kg

⇒ mass = 1.16 kg

===========================================================

On comparing Box 1, Box 2, and Box 3, we understand that Box 1 has the smallest mass
