Question

You throw a stone with a force of 55.1 N. It accelerates at 41.6 m/s2.

Find the mass of the stone in kg. Round your answer to 1 decimal place.

Answer 1

Mass = 1.3 Kilograms.

Explanation:

Given the following data;

Force = 55.1 N

Acceleration = 41.6 m/s²

To find the mass of the stone in kg;

Newton's Second Law of Motion states that the acceleration of a physical object is directly proportional to the net force acting on the physical object and inversely proportional to its mass.

Mathematically, it is given by the formula;

Force = mass * acceleration

Substituting into the formula, we have;

55.1 = mass * 41.6

`Mass = \frac {55.1}{41.6}`

Mass = 1.3 Kilograms
