Physics

Mass, m = 16.02kg

Explanation:

Given the following data;

Force, F = 157N

Since it's a free fall, acceleration, a = g = 9.8m/s² (acceleration due to gravity).

To find the mass;

Force is given by the multiplication of mass and acceleration.

Mathematically, Force is;

F = ma

Where;

F represents force measured in Newton.m represents the mass of an object measured in kilograms.a represents acceleration measured in meter per seconds square.

Making mass (m) the subject of formula, we have;

$Mass (m) = \frac{F}{a}$

Substituting into the equation;

$Mass (m) = \frac{157}{9.8}$

Mass, m = 16.02kg

Therefore, the mass of the rock is 16.02kg.
