Question: A carpenter swings a 3-kg hammer so that its speed is 5 m/s just before it strikes a nail. The nail is driven 6 mm into a block of wood. Assuming that a constant force resisted the motion of the nail, what must have been the magnitude of the force? The response must be typed, single spaced, must be in times new roman font (size 12) and must follow the APA format.
