A force f acts on a 10kg object at rest for 3s and changes
A force F acts on a 10kg object at rest for 3s and changes its velocity to 6m/s. What is the change in momentum of the object? What is the impulse of the force on the car? Using the fact that impulse is equal to the change in momentum find F.
