Question

a student weighing 490 N stands on a spring scale on earth. what is the students mass(gravity is 9.8 m/s

Answer 1

Answer:

Mass, m of the student is 50kg.

Explanation:

Given the following data;

Weight of student = 490N

Acceleration due to gravity = 9.8m/s

Weight is the product of the mass of an object or body multiplied by gravity.

Mathematically, weight is;

$W = mg$

Where;

W represents the weight of a body measured in Newton.

m represents the mass of a body measured in kilograms.

a represents acceleration due to gravity measured in metre per seconds.

$m = \frac{W}{g}$

$m = \frac{490}{9.8}$

Mass, m = 50kg.

Therefore, the mass of the student is 50kg.
