A 0.450-kg hammer is moving horizontally at 7.00 m/s when it strikes a nail and comes to rest after driving the nail 1.00 cm into a board. (a) Calculate the duration of the impact. (b) What was the average force exerted on the nail?
Step-by-step solution In this problem a hammer strikes a nail and comes to rest calculate the duration of the impact and the average force exerted on the nail. Step 1 of 5 The change in momentum over a range of certain time is nothing but average force acting on it.
