A 100 N force has a horizontal component of 60 N and a vertical component of 80 N. The force is applied to a 10 kg box which rests on a level floor whose coefficient of friction is 0.1. The cart starts from rest, and moves 2.0 m horizontally along the floor.
What is the cart's final velocity?
The final answer is 3,23 m/s, but I need a detailed explaination of how to get to that point.
