Textbook Question
Chapter 3, Problem 1RCQ
Which has greater momentum: an automobile at rest or a moving skateboard?
Expert Solution & Answer
To determine
The object with greater momentum.
Answer to Problem 1RCQ
The moving skateboard has greater momentum than the automobile at rest.
Explanation of Solution
Express the formula to calculate the momentum.
- p is the momentum
- m is the mass.
- v is the speed.
Since the automobile is at rest, its speed is zero. Hence, its momentum is zero. The skateboard which is moving with some speed will have momentum.
Conclusion:
The moving skateboard has greater momentum than the automobile at rest.
