Chapter 9.1, Problem 10SSC

To determine

Which has the greater momentum.

Answer to Problem 10SSC

Falling rain drop has more momentum than parked truck.

Explanation of Solution

Introduction:

Momentum of any object is the product of mass of that object and velocity.

As it is given that truck is parked it means it is at rest position and hence its velocity is 0.

Since the velocity of truck is 0, therefore its momentum will be also 0.

Now, in case of falling raindrop, it has some mass and also velocity therefore falling rain drophas some momentum.

Conclusion:

Therefore, falling rain drop has more momentum than parked truck.
