Find the momentum of a 15 kg object traveling at 7 m/s.

The momentum of an object is found by using the following formula:


\displaystyle p=mv

  • P is the momentum and is measured in kg · m/s
  • m is the mass and is measured in kg
  • v is the velocity and is measured in m/s

In this question, the object is 15 kg and is travelling at 7 m/s. That means the mass is 15 kg and the velocity is 7 m/s.

Since all the needed variables are found, substitute it into the equation:


\displaystyle p=mv \rightarrow p=15 * 7

Multiply:


\displaystyle p=105\ kg * m/s

__________________________________________________________

What is the momentum? 105 kg · m/s

What is the velocity? 7 m/s

What is the mass? 15 kg

What equation did you use to solve? p = mv
