Question

A person with a mass of 15 kg is walking on a flat surface at a velocity of 5 m/s. What is the walker's momentum?

A. 3 kg-m/s
B. 0.3 kg-m/s
C. 20 kg-m/s
D. 75 kg-m/s

Answer 1

d

velocity multiplied to mass

Answer 2

Momentum of the person, p = 75 kg-m/s

Step-by-step explanation:

It is given that,

Mass of the person, m = 15 kg

The person is moving with a velocity of, v = 5 m/s

We need to find the walker's momentum. It is equal to the product of mass and velocity with which it is moving. Mathematically, it is given by :

p = mv

`p=15\ kg* 5\ m/s`

p = 75 kg-m/s

So, the momentum of the person is 75 kg-m/s. Hence, this is the required solution.
