A box with mass 4.0 kg is pulled from rest along a horizontal floor by a constant force F. A constant frictional force of 1.0 N acts on the box. When the box has travelled 1.0 m its velocity is 1.5 m / s. The kinetic energy of the box is equal to the work done on the box. What is force F?

1. A2.0 N
2. B3.5 N
3. C4.0 N
4. D5.5 N
