To find the mass, with only the weight:
⇒ must consider the relationship between the mass and weight
⇒ (in other words) we must find the equation that has both the
mass and weight
Based on our physics knowledge, we know:
[tex]Weight=mass*gravitational_. acceleration[/tex]
- Weight: 147N
- Gravitational Acceleration: 9.8 m/s²
Now let's plug in the values, and solve:
[tex]147N = mass*9.8_.m/s^2\\mass = 15_.kg[/tex]
Answer: 15 kg
Hope that helps!
*as a note, if you use the gravitational acceleration as 10m/s², then the answer would be 14.7 kg
