Aperson 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

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

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 = 75 kg-m/s

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