An object has a velocity of $+3.0\,\text{m s}^{-1}$. A force is applied to the object. Later, its velocity becomes $-4.0\,\text{m s}^{-1}$. The object's mass is $5.0\,\text{kg}$. What is the change in momentum of the object?
- A$-35\,\text{kg m s}^{-1}$
- B$-5.0\,\text{kg m s}^{-1}$
- C$+5.0\,\text{kg m s}^{-1}$
- D$+35\,\text{kg m s}^{-1}$
