A body of mass $0.80\,\text{kg}$ moves along a straight path with a velocity of $2.0\,\text{m s}^{-1}$. A force acts on the body, in the same direction as its motion, for $1.0\,\text{minute}$, and its velocity then increases to $6.0\,\text{m s}^{-1}$. What force is exerted on the object?
- A$0.053\,\text{N}$
- B$0.080\,\text{N}$
- C$3.2\,\text{N}$
- D$4.8\,\text{N}$
