8. 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?

The correct answer is 75 kg m/s.

Explanation:

The expression of the momentum in terms of velocity and mass is as follows;

p=mv

Here, m is the mass of the object and v is the velocity.

It is given in the problem that a person with a mass of 15 kg is walking on a flat surface at a velocity of 5 m/s.

Calculate the walker's momentum.

Put m= 15 kg and v= 5 m/s in the above expression.

p=(15)(5)

p= 75 kg m/s

Therefore, the momentum of the speedboat is 75 kg m/s.

answer: decibel
