Chapter 2, Problem 38R

To determine

To Choose: The correct option.

Answer to Problem 38R

Option (A) is the correct answer.

Explanation of Solution

Given:

Velocity of the entire object such as car, mouse, bug and bicycle are equal.

Formula used:

The equation for momentum can be expressed as,

  $p=mv$ ........ (1)

Here, $m$ and $v$ are mass and velocity of the object.

Calculation:

From the above equation, it is evident that momentum of an object is the product of mass and velocity. If the velocity of the entire given object is same, then greater the mass of the object, larger would be the momentum. From the given objects, bicycle, mouse and bug have smaller mass when compared to mass of car. Therefore, car will have greater mass hence it has greater momentum.

So, option (B), (C) and (D) are wrong.

Conclusion:

Hence, momentum of a car will be greater.
