A student has six textbooks, each with a thickness of 3.6 cm and a weight of 38 N. What is the minimum work the student would have to do to place all the books in a single vertical stack, starting with all the books on the surface of the table?
Already answered above. Be sure to read through everything I wrote. Don't just eye on the answer. Read and make sure you understand everything and if not ask again. And before posting any questions like this be sure add in your post what things you don't understand or are having a hard time with like I did with mine. Because if you post questions like this then we will not know what you have done to find the answer or why you are having troubles with it.
