The mass of a hockey puck remains the same throughout almost all levels of ice hockey, including NHL games and international play, such as the Olympics and the World Championships. The block starts from rest and moves a distance 12.5 min a time 4.50 s. (a) What is the mass of the block of ice, A dockworker applies a constant horizontal force of 88.0 N to a block of ice on a smooth horizontal floor. A dockworker applies a constant horizontal force of 80.0 N to a block of ice on a smooth horizontal floor. While it has made a few changes over the years, the ice hockey puck has always been an imperative part of the game. They use vulcanized rubber to make hockey pucks. If ice friction and air resistance are neglected, the force required to keep the puck sliding at constant velocity is a) equal to its mass times its weight b) equal to its weight. Determine the coefficient of friction between puck and ice.
