A block with a mass of 20.0 kg rests on a flat surface with a coefficient of kinetic friction of 0.4. The object is pulled with a force of 60.0 N which forms an angle θ = 60 degrees to the horizontal direction. If the object moves 20.0 m in the horizontal direction, how much work does the force do and how much work does the friction force do?
