Question

Which object has the greatest momentum?
Select one:
a. An 18-wheeler tractor trailer at rest.
b. An average mass person walking.
C. A sports car driving on the highway.
d. A baseball thrown by a professional​

Answer 1

Answer:

option d is correct answer I think so

Answer 2

Answer:

The correct answer is option c. A sports car driving on the highway.

Concept:

Linear momentum: It is defined as the mass in motion. It is the product of the mass and velocity of a moving object. Mathematically it can be expressed as,

p = mv

Where p = linear momentum

m = mass of the object

v = velocity of the object

Explanation:

We will check all the options one by one.

a. An 18-wheeler tractor-trailer at rest.

It is at rest, so it will not have any momentum and hence this option is wrong.

In b, c and d, the objects are moving. So, they all will have some value of momentum.

Now from the formula p = mv, we can conclude that the more the mass of the object, the more will be its momentum.

Among the three objects (Average mass person, sports car, and baseball) sports car is having largest mass and its velocity is also very high. Hence, the sports car will have the greatest momentum.

So, option c. is the correct answer.
