The weight of a body is 147N. what is its mass?

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
