Question
Chapter 7, Problem 2Q
To determine
To explain: The effect on the momentum of person who jumps from a tree on to the ground.
Expert Solution & Answer
Explanation of Solution
Introduction:
Momentum is the mass times the change of velocity of an object. It is vector quantity.
When person jumps from the tree his velocity goes on increasing before striking on to the ground. As change in velocity is goes on increasing, the change in momentum is large. The person’s momentum is transferred to the ground. But this momentum is small. So, momentum of Earth does not change.
Conclusion:
The momentum of the person transferred to the ground.
