On a given planet, the weight of an object varies directly with the mass of the object. Suppose that an object whose mass is 9 kg weighs 36N . Find the weight of an object whose mass is 4 kg
To solve this problem, we can use the formula for direct variation, which is:
Weight = k * Mass
where k is the constant of variation.
We are given that when Mass = 9 kg, Weight = 36 N. Let's use this information to find k:
36 = k * 9
k = 36 / 9
k = 4
Now that we have k, we can use it to find the weight of an object with a mass of 4 kg:
Weight = 4 * 4
Weight = 16 N
Therefore, the weight of an object with a mass of 4 kg on this planet is 16 N.
