Question

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 54 N. calculate the mass of another object that weighs 24 N​

Answer 1

We can use the proportion method here

Mass Weight
9 kg 54N
(?) 24 N

Now since it is “directly varied” we can cross multiply to get:

54*x = 24*9
54*x = 216
x= 4

Ans: The mass of an object weighing 24 N is 4 kg
