Question

# A point-like object of mass 2.0 kg moves along the x-axis with a velocity of + 4.0 m/s. A net horizontal force acting along the x-axis is applied to the object with the force-time profile shown. What is the total work that was done by the force?

- 20 J
- 25 J
- 65 J
- 81 J

## The correct answer is: 65 J
