On a given planet, the weight of an object varies directly with the mass of the object. Suppose that an object whose mass is 4 kg weighs 12N Calculate the mass of another object that weighs 15N

Answer 1

To find the mass of another object that weighs 15N, we need to set up a proportion:

Mass / Weight = Mass / Weight

Let's call the mass of the second object M2:

4 kg / 12N = M2 / 15N

Now, we can cross multiply:

4 * 15N = 12N * M2

Simplifying:

60N = 12N * M2

Divide both sides by 12N:

60N / 12N = 12N * M2 / 12N

5 = M2

The mass of the other object would be 5 kg.
