A hammer of mass m = 0.44 kg is moving horizontally at a velocity of v = 4.5 m/s when it strikes a nail and comes to rest after driving the nail a distance Δx = 0.85 cm into a board. Part A : What is the duration of the impact, assuming the acceleration is constant during this time period, in terms of the given variables? Part B: What was the average force exerted on the nail, in terms of the mass, initial velocity, and distance traveled? Part C: What was the average force, in newtons, exerted on the nail?
