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
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.
