A crazy anti-textbook Pearson rep goes ape and tries to chop a 6.0 cm thick textbook in half to show you how books and written homework can be damaged, while your online work can never be damaged. If the 22 kg axe head reaches the book cover at a speed of 34 m/s chopping completely through the book before coming to a stop, what force did the book exert back while it was being cut?
You work for a moving company and are given the job of moving two crates (masses are 130kg and 280kg) held together by a rope attached between the two. You pull on a rope attached to the larger crate giving the system the acceleration of 0.29m/s2. Wh..
