What Is The Mass Of Sack Of Rice That Has A Weight Of 650n?

What is the mass of sack of rice that has a weight of 650N?

 

Answer:

The mass of 650-N sack of rice is 66 kg.

Explanation:

Based on the Newtons Second Law of Motion, force is directly proportional to mass and acceleration.

 

F = ma

Mass is inversely proportional to acceleration

Therefore:  

m = F/a

Where:  

F = force  (Newton = kg·m/s²)

m = mass  (standard unit: kilograms)

a = acceleration

1 Newton = 1 kg·m/s²

Given:  

F = 650 Newtons

650 Newtons = 650 kg·m/s²

a = acceleration due to gravity = 9.8 m/s²

Find the the mass:

m = F/a

m = (650 kg·m/s²) / (9.8 m/s²)

m = (650 kg·m/s²) × (1 s²/9.8 m)

m =  66.3 kg.

m = 66 kg.

The mass of 650-N sack of rice is 66 kg.
