Question

You can find the net force F on an object

by using the formula F = ma, where m is
the mass of the object in kilograms and
a is its acceleration in meters per second
squared. What is the mass of an object
that has a net force of 65 kg m/s² and an
acceleration of 5 m/s²?

Answer 1

Answer: m = 13 kg

Explanation:

This question gives us the formula to use. We will plug-in the values we know and solve for the unknown (mass).

Given:

F = ma

Plug-in known values:

(65 kg m/s²) = m(5 m/s²)

Divide both sides of the equation by 5 m/s²:

The m/s² unit cancel out, so we are left with kg.

m = 13 kg

The mass of the object is 13 kg.
