When a hammer strikes a nail, it is compressed along its length. Suppose that a steel nail 10.00 cm long and 3.00 mm in diameter is compressed an average of 65.0 µm by a 0.415 kg hammer during a 1.20 ms collision.
(a) What average force was exerted on the nail by the hammer?
(b) What is the impulse imparted to the hammer?
(c) If the hammer is moving at 7.00 m/s just before the collision, what is its final velocity?
