2) A mass of 8 kg has a force of 42 Newtons applied to it in the +x direction on a horizontal surface with friction. It has overcome static friction and moves 4 meters over the surface with friction. What is the work done by the normal force and the weight in Joules? In other words, determine the work done by the weight and normal force and add them together.
Homework Answers
The given mass is moving on a horizontal plane .The weight and normal force are acting in the vertical direction. Therefore the displacement is perpendicular to the weight and normal force. Therefore work done by weight and normal force is zero since they act in the direction perpendicular to the displacement direction

1) A mass of 8 kg rests on a floor with friction. One force is applied vertically downward of 21 Newtons and another force is applied in the +x direction such that it just begins to move the mass. The force of 21 Newtons is then applied vertically upwards instead of downwards and another force is applied in the +x direction which just begins to move the mass that force is 137 Newtons less than the first case. What is...
