In a garden nursery a large box of flower seeds (mass 18kg) is pushed 1.6m along a horizontal floor by a woman who is exerting a force of 1.5E2 N at 22o below the horizontal. The coefficient of kinetic friction between the box and the floor is 0.55. a) Use Newton's laws of motion to determine the magnitudes of the normal force and friction force on the box. b) use conservation of energy to determine the final speed of the...
