A train car of mass 16,500 kg moves along the railroad track with a constant speed of 14 m/s. What is the momentum of the car?

Explanation:

Here,

Mass=16,500kg.

speed=14 m/s.

we know that,

⠀

where,

p=momentum

m=mass

v=velocity

according to the question,

⠀

⠀

⠀

so,

velocity of the car is 231000kg.m/s

it has to be b, about 97 percent.
