Question

Which of the following balls will have the highest momentum, if all of them have the same mass?

• A. Ball D: velocity = 2 m/s
• B. Ball B: velocity = 5 m/s
• C. Ball C: velocity = 14 cm/s
• D. Ball A: velocity = 2.5 m/s

Answer 1

The correct option is B Ball B: velocity = 5 m/s

The momentum of any object is directly proportional to its mass and velocity.
In the given scenario, as the mass of all the balls is the same, the momentum of the balls is directly proportional to their velocities.
The larger the velocity, the greater will be its momentum.
Ball B has the maximum velocity. Hence, it will have the highest momentum.
