Chapter 2, Problem 19Q

To determine

To explain: Whether an object has zero velocity and non zero acceleration at the same time along with an example.

Answer to Problem 19Q

Yes, it is possible to have zero velocity and non-zero acceleration at the same time. An object which is thrown in vertically upward direction can have zero velocity and nonzero acceleration at a point.

Explanation of Solution

Introduction

Velocity: The rate of change distance with time

Acceleration: The rate of change of velocity with time.

Yes, it is possible to have non acceleration but zero velocity at the same time. When an object is thrown vertically upward then velocity of an object becomes zero at the peak point but still acceleration due to gravity acts on an object at that peak point. Hence, an object which is thrown in vertically upward direction have zero velocity but nonzero acceleration at peak point.
