Chapter 7, Problem 9Q

To determine

To explain: The possibility for an object to receive a larger impulse from a small force in comparison to a large force.

Explanation of Solution

Introduction:

Impulse is the product of impact force and time applied. As force is a vector quantity, impulse is also a vector quantity.

For a large force impulse is high, but small force also produces large impulse. If small force is applied on an object for a long time, then large impulse is obtained. This impulse is greater than the impulse from large force applied for a small time. This application of impulse is used for safety and to avoid injuries. Use of air bags in a car, increases the time of collision. This decreases the force of impact.

Conclusion:

Yes, it is possible to obtain larger impulse from a small force than for large force, if the time of impact of force is large.
