Answer:
Box 1
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
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
