(e) A 0.55 kg hammer is moving horizontally at 7.1 m/s when it strikes a nail and comes to rest after driving the nail 0.012 m into a board. What is the duration (in seconds) of the impact? Keep 2 Non-zero digits in the decimal. (Hint: use 1D kinematics)

Calculate the magnitude of the average force (in Newtons) on the hammer using the Impulse-Mometum theorem

Calculate the magnitude of the average force (in Newtons) on the hammer using the work - KE theorem.
