In Alamogordo, New Mexico, falling rocks are a hazard along US Highway 82. If a rock falls from a cliff with 157 N of force, what was the mass of the rock?

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;

Where;

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

Substituting into the equation;

Mass, m = 16.02kg

Therefore, the mass of the rock is 16.02kg.
