Explanation:
A karate expert executes a swift blow and breaks a cement block with her bare hand. There is a collision between the block and her hand.
Impulse is the change in the momentum of an object when the object is acted upon by a force for a short interval of time.
The time of impact on both the karate's expert of hand and the cement block is same. The force on both karate expert's hand and the cement block have the same magnitude. Therefore, the impulse is same. Only the velocity and acceleration change can differ for two colliding objects between the block and her hand.
The magnitude of the force experienced by her hand is identical to the force applied to the block.
The cement block collides with the expert's hand, so the magnitude of the force on both the objects will depend on the impulse of both objects which will be the same because the impact time is the same for both objects.
The magnitude of the force experienced by the expert's hand is equivalent to the force applied to the block.
What is the force?
A force can be defined as a result of a push or pull upon an object when the object has interacted with another object.
Given that a karate expert executes a swift blow and breaks a cement block with her bare hand.
For the given situation, two objects are one is cement block and the other is expert's hand. A collision s taking place between the block and her hand.
Impulse is a certain amount of force applied for a certain time to cause a change in momentum. So for this collision, the impact time is the same for both objects also the change in momentum will be same. So the magnitude of the force on both objects will be the same.
Hence we can conclude that the magnitude of the force experienced by the expert's hand is equivalent to the force applied to the block.
