Answer to Question #286376 in Molecular Physics | Thermodynamics for mimi

Question

An object weighs 294.9N on a planet where the acceleration due to gravity is 4.9m/s². What is its weight (in N) on earth?

Answer 1

Let's first find the mass of the object:

$$m=\dfrac{W}{g}=\dfrac{294.9\ N}{4.9\ \dfrac{m}{s^2}}=60.18\ kg.$$

Finally, we can find the weight of the object on Earth:

$$W=mg=60.18\ kg\times9.8\ \dfrac{m}{s^2}=589.76\ N.$$
