Example 4.1 You slowly lift a book of mass 2 kg at constant velocity a distance of 3 m. How much work did you do on the book? Solution. In this case, the force you exert must balance the weight of the book (otherwise the velocity of the book wouldn"t be constant), so F = mg = (2 kg)(10 m/s 2) = 20 N.
