PLEASE HELP!! EXPLAIN YOUR ANSWER PLEASE! :)

A meteor comes hurtling toward Earth and lands near a lake. The meteor weighs 3,204 N. What is the mass of this meteor?

A) 326.9 kg
B) 31,399.2 kg
C) 3.06 kg
D) 3,204 kg

Answer 1

The formula for force is F=ma. Because weight is a measure of force, then we can substitute the weight of the meteor, 3204 N, for F in the the equation for force. We also know that the acceleration of gravity on Earth is 9.8 m/s^2. To find the mass, simply divide both sides of the equation by the value of acceleration to get

`m = (f)/(a) = (3204)/(9.8) = 326.9`
Therefore, the value of the mass of the meteor is 326.9 kg.
