A lot more than Q = FS = 40*10 = 400 Joules. Why? Because she also has to change the diapers…ar ar ar. BTW Q = FS cos(theta) is the so-called work function. It’s important to learn the work physics; you’ll see it over and over in science/physics class. Theta is the angle between the force vector F and the distance vector S. In your problem we assume theta = 0, the two vectors were assumed aligned.... Show More
