Impulse:
Impulse is defined as the change in momentum of an object when a force is applied to it for a certain amount of time. Mathematically, impulse can be calculated using the formula:
Impulse = Change in Momentum
Explanation:
1. Initial momentum:
When the body of mass m hits the wall with velocity v, its initial momentum is given by:
Initial momentum = mass x velocity = m x v
2. Final momentum:
After bouncing back, the body still has the same velocity v, but in the opposite direction. Therefore, its final momentum is given by:
Final momentum = mass x final velocity = m x (-v) = -m x v
3. Change in momentum:
The change in momentum of the body is the difference between its final and initial momentum. In this case, it is given by:
Change in momentum = Final momentum - Initial momentum = (-m x v) - (m x v) = -2m x v
4. Impulse:
The impulse experienced by the body is equal to the change in momentum. Therefore, the impulse is:
Impulse = Change in momentum = -2m x v
The negative sign indicates that the impulse is in the opposite direction to the initial momentum of the body.
Conclusion:
When a body of mass m hits a rigid wall with velocity v and bounces back with the same velocity, the impulse experienced by the body is -2m x v. This impulse is in the opposite direction to the initial momentum of the body.
