A vase was placed on the coffee table. The coefficient of static friction between the vase and the table is 0.4176, whereas the coefficient of kinetic friction is 0.2082. The vase weighs 1.29667kg. A cat decided to redecorate the room by pushing the vase off the table. As the cat pushes the vase with its paw, the vase moves. Then, the cat maintains a constant applied force of 8.904N on the vase in the positive x-direction. What is the acceleration...
