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.

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.

inverse v=i*r
