Question

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?

Answer 1

Step-by-step explanation:

Here,

Mass=16,500kg.

speed=14 m/s.

we know that,

`\tt{ p=m×v }` ⠀

where,

p=momentum

m=mass

v=velocity

according to the question,

`\tt{ momentum =mass×velocity }` ⠀

`\tt{ 16500×14 }` ⠀

`\tt{ 231000~kg.m/s }` ⠀

so,

velocity of the car is 231000kg.m/s
