Chapter 16, Problem 1A
What would be the momentum of an object if it were pushed to the
Expert Solution & Answer
To determine
The momentum of an object if it were pushed to the speed of light.
Explanation of Solution
Introduction:
Newton's second law states that rate of change of momentum is proportional to applied force.
Change in momentum of an object is equal to applied impulse. If anyone doubled the impulse, momentum gets doubled.
Momentum equals mass times the velocity.
If the object speed increased to speed of light then its momentum becomes infinite. For this it requires infinite impulse which is practically impossible.
Conclusion:
The momentum of the object becomes infinite when it pushed to the speed of light.
