a 5.0 kg textbook is raised a distance of 30.0 cm as a student prepares to leave for school. how much work did the student do on the book?
please show work
Homework Answers
so boy have to exert a force equal to 5g to raise it
so
F = 5g = 5X9.81 = 49.05 N
work done = F X h = 49.05N X (30/100)m = 1.47 J
