Chapter 16, Problem 2A

To determine

To Explain: The rest mass.

Explanation of Solution

Introduction:

Mass is the quantity of matter contained in the object. Inertia of any body is the property or tendency of the body to be at state of rest unless one any force is applied on it.

Rest mass is the inertial mass: which it has at state of rest. Actual mass of the object is determined by using a formula,

  $m=\frac{m_0}{\sqrt{1-\frac{v^2}{c^2}}}$

Where,

m is actual mass of the body.

  $m_0$ is the rest mass

v is velocity of the object.

c is the speed of light.
