Chapter 2, Problem 20Q

To determine

To explain: Whether an object can have zero acceleration and non zero velocity along with example.

Answer to Problem 20Q

Yes, it is possible to have zero acceleration and non-zero velocity at the same time. The example is an object having uniform velocity.

Explanation of Solution

Introduction:

The acceleration of an object is defined as the rate of change of velocity.

  

The acceleration of an object is zero.

So,

  $\begin{array}{l}a=\frac{dv}{dt}\\ a=0\\ \frac{dv}{dt}=0\\ v=\text{constant}\end{array}$

The velocity is constant, in case of zero acceleration. This means when there is no change in velocity then acceleration will be zero. Thus, it is possible to have non zero velocity and zero acceleration at the same time

For example: An object having uniform velocity.
