- 15. Leroy and Mike are sliding a 72 kg couch with a 26.00 kg child sitting on it down a 25.0 m hallway. Leroy is pulling from the front with a force of 112 N while Mike pushes from behind with a force of 154 N. The couch has a frictional force of 243 N pulling it back. If the couch starts from rest: [7 marks] a) How long does it take them to reach the end of the hallway? b) How fast are they moving once they reach the end of the hallway?5.
