Power As shown in the picture below, you and a friend are pushing a box horizontally. You can assume that you and your friend are both pushing completely horizontally in this case. Your combined push force (from you and your friend) is Push = 46.0 N. The box has a mass of 20.0 kg. You and your friend push the box a horizontal distance of 6.50 m. There is a force of friction between the ground and the box with a value of f = 28.0 N. Assume that initially the box is at rest when you and your friend start pushing it. What is the rate at which all of the forces do work on the box? This is another way of asking about Power. You'll need acceleration to find the time - but you have enough information to calculate the acceleration.
