Question

Another physics question, this one about Net Force and Weight, once again I'm a Sophmore

"If Simba weighs 687 N on Earth, what is his mass?"

And these are the answers
a) 70.0kg
b) 677kg
c) 687kg
d) 6.74 x 10^3 kg

Answer 1

m = 70 kg

Step-by-step explanation:

We have,

Weight of Simba on Earth is 687 N

It is required to find his mass.

The net force acting on him is the force of gravity or its weight. It is given by :

`W=mg\\\\m=(W)/(g)\\\\m=(687)/(9.8)\\\\m=70\ kg`, g = 9.8 m/s²

So, his mass is 70 kg.
